Advanced shape based painter example

[ddabrahim]

Updated the example to comply with latest guidelines

Replaced number variables with boolean variables where it was reasonable to do so Made sure all variables declared in the variables editor Added extra comments and events groups to make it more simple to follow how the example works Added RGBA letters to color selection lines.

Project was corrupted and didn't worked in the web editor, it was working in the desktop editor due to pure luck I think. what I have done to fix it:

Variable types in the variable editor was wrong Replaced old variable events with the new variable events Some variable expressions were also wrong, was calling a number variable when it was a string variable (RGBA). Changed object names to remove errors regarding being the same as variable names.
