Merge 3.0 refactoring

## What's Changed
* Complete refactoring using spectre.css and correct Preact API per @alexblog suggestion
* Smaller footprint
* Add support for extensions/pluggins
* Add theme support by using external css
* Remove banner as unnecessary
* Remove information bar and put information to separate page and respective panel
* Add audio and haptic feedback
* Add Repetier / ESP3DLib V2 / Smoothieware / GRBL support
* Split code for 3DPrinter / CNC / Sand Table

## Limitations
* CNC / Sand Table specific UI is still not defined
* Wizard is not implemented yet
* Works with ESP3D 3.0- alpha-2 - no backward compatibility
* Language packs are not ready to be translated yet as UI is not finished

+1 - key : Settings
+2 - value: array of data formated like this
+{"F":"network/network","P":"130","T":"S","V":"esp3d","H":"hostname","S":"32","M":"1"}
+or 
+{"F":"service/notification","P":"1004","T":"B","V":"1","H":"auto notif","O":[{"no":"0"},{"yes":"1"}]}
+
+F: is filter formated as section/sub-section, if section is same as sub-section, it means no sub-section
+P: is id (also position reference so it is unique)
+T: is type of data which can be:
+S: for string
+I: for integer
+T: for Byte
+A: for IP address / Mask
+V: is current value, if type is string and value is ********, (8 stars)then it is a password
+H: is label of value
+S: is max size if type is string, and max possible value if value is number (byte, integer)
+M: is min size if type is string, and min possible value if value is number (byte, integer)
+MS: is additionnal min size if type is string (e.g for password can be 0 or 8, so need additional min size), M should be the more minimal value
+so MS value must be between M and S 
+O: is an array of {label:value}
+R: need restart to be applied
+
+Note: currently there is no float value so far, if needed a new type will be added in futur - TBD, 
+Note2 : the 2.1 Flag type is no more used, several entries are used instead grouped by sub-section
