Benoît Minisini a2850ebc91 [CONFIGURATION]
* BUG: Do not compile database manager anymore, it has been deprecated.
* BUG: Compile the gb.dbus component.

[INTERPRETER]
* NEW: Pointer is a real datatype now.
* NEW: Static arrays came back. They are now like real array classes, 
  except that they are not resizable.
* NEW: IsPointer() is a new function that tells if an expression is a 
  pointer.
* NEW: All XXXX?() function synonymous were removed. Use the IsXXXX() 
  version instead.
* NEW: Remove now useless source files.

[COMPILER]
* NEW: Static arrays came back, with actually the same syntax as before.

[EXAMPLES]
* BUG: Fix the examples according to the new array syntax.
