Fully replace the safety regs with those from the SR2020.5 rules

The regs which were here appear date to a previous version of the
kit and are incompatible with the current version. Surprisingly
this appears to have already been the case when they were added
to this repo, though that appears to have been missed at the time.

This commit introduces the regulations as they were in the SR2020.5
tag of the rules (the last published version before the move to
HTML format).

 We recommend that you bear these regulations in mind during development too, although it’s not always possible to meet them while building and testing your robot.
 
 The following procedure will be used when testing a robot:
-- Check that there is a battery installed in the robot.
-- Check that any additional power sources have already been authorised.
-- Check that the battery cable originally provided by Student Robotics is being used to connect the power board to the battery. If not, check that the replacement has suitable rating and quality.
-- Leaving the battery physically installed, unplug the deans connector.
-- Check the battery’s mounting holds the battery securely, and does not expose the battery to sharp edges.
-- Check that the battery’s casing is rigid, and strong – i.e. bubble wrap is not suitable.
-- Locate the large green power connector that connects the battery to the power board. In turn, give each of the wires that enter it a gentle tug. The cables must not move.
-- Check that there is not an excessive amount of unshielded wire protruding from the large green power connector.
-- Check that the cable between the large green power connector and the deans connector is not damaged. The sheath must not have any holes in etc.
-- Check that the cables between the power board and body of the battery do not pass through areas of the robot that could cause them to be damaged by moving mechanical parts.
-- Check that only the power board is connected to the battery (if the deans connector were currently connected).
-- Check that the power switch on the power board is easily accessible.
-- Check that all electronics are securely fixed to the robot.
-- Check for unreasonably sharp edges and dangerous moving parts.

+1. Check that the parts of the robot that were provided by Student
+   Robotics are in a safe condition. If any of the following criteria
+   are not met, the offending component must be replaced with one in
+   suitable condition, and the procedure restarted from the beginning.
+
+    1. Check that the cables between the power board and body of the
+       battery are not damaged. The sheath must not have any holes in
+       it.
+
+    2. Locate the yellow XT60 connector pair that joins the battery to
+       the cable leading back to the power board. Check that the
+       insulation surrounding these connectors and the attached wiring
+       is undamaged.
+
+    3. In turn, give each of the wires attached to these connectors a
+       gentle tug. The cables must not move relative to the connectors.
+
+    4. Locate the metal terminals that connect the battery cable to the
+       power board. Check that the insulation surrounding these
+       terminals and the attached wiring is undamaged.
+
+    5. In turn, give each of the wires attached to these terminals a
+       gentle tug. The cables must not move.
+
+2. Check that the parts of the robot that were built by the competitors
+    are in a safe condition. If any of the following criteria are not
+    met, the team must be instructed to make amendments to the robot.
+
+    1. Check that there is a battery installed in the robot.
+
+    2. Check that any additional power sources have already been
+       authorised.
+
+    3. Leaving the battery physically installed, unplug the XT60
+       connector.
+
+    4. Check the battery's mounting holds the battery securely, and
+       does not expose the battery to sharp edges.
+
+    5. Check that the battery's casing is rigid, and strong -- i.e.
+       bubble wrap is not suitable.
+
+    6. Check that the cables between the power board and body of the
+       battery do not pass through areas of the robot that could cause
+       them to be damaged by moving mechanical parts.
+
+    7. Check that only the power board is connected to the battery (if
+       the XT60 connector were currently connected).
+
+    8. Check that the power switch on the power board is easily
+       accessible.
+
+    9. Check that all electronics are securely fixed to the robot.
+
+    10. Check for unreasonably sharp edges and dangerous moving parts.
