Benoît Minisini 3d80d44a4a [WIKI CGI SCRIPT]
* BUG: Some little layout fixes.

[INTERPRETER]
* OPT: Read the user home directory only if the current uid has changed. 
  Otherwise, cache it into memory.
* OPT: String memory management has been optimized.
* OPT: Some little optimizations there and there.
* NEW: A new interpreter option, "-k", that prevents shared library to be
  unloaded until the process terminates. That can be useful when 
  debugging with valgrind.
* OPT: System.Language property was optimized.
* OPT: The gb_error.c file is now compiled with -O3.

[GB.GTK]
* BUG: Disable the management of input methods in TextBox and TextArea
  controls, so that the input methods are not disturbed. Consequently;
  SCIM and Bridged SCIM work again.
* BUG: You can read keyboard events properties in a Form KeyPress or 
  KeyRelease event handler correctly now.
