Move to the First Breakpoint After Clicking Debug

[jmwright]

From a conversation with Ferdinand:
"Perhaps it would be an idea to execute the code up to the first breakpoint when clicking debug"

Currently, the editor stops executing on the first line of the script when the user clicks the debug button. It might be better if it moved to the first breakpoint. The drawback of doing this is that the user has to put a breakpoint on the first line of the script if they want to walk through line-by-line.
