Benoît Minisini 7b01d12f31 [INTERPRETER]
* OPT: Optimizations in string comparison operators.
* OPT: Optimizations in string allocations.
* OPT: Optimizations in Left$(), Mid$(), Right$() and Len().
* OPT: Optimizations of calls to native methods when the number of 
  arguments is fixed, and when no argument conversion is needed.
* OPT: Optimizations of INPUT and LINE INPUT, by using an internal buffer
  instead of reading the stream one byte at a time.
* BUG: Fixed the new error management.
* BUG: Fixed a possible spurious error when reading a file from an archive.

[GB.EVAL]
* BUG: Use the same new error management than the interpreter.

[GB.QT]
* BUG: The DrawingArea control now should draw its border correctly without
  erasing its contents.
