Benoît Minisini b3db598050 [DEVELOPMENT ENVIRONMENT] 
* BUG: Breakpoints are correctly reset when opening a new project.

[INTERPRETER]
* BUG: The GB.NewString(), GB.NewZeroString() and GB.TempString() API 
  signature has changed. All components have been updated accordingly.
* OPT: Many optimizations to speed up the interpreter.

[GB.EVAL]
* NEW: During syntax highlighting, the first character of class names is
  automatically converted to uppercase.
