* Script Editor: altered keyboard shortcut Ctrl-X to Ctrl-Q (to avoid
  masking the common cut text shortcut).
* Script Editor: if editor is used in live-mode, inform the sampler that
  it needs to automatically reload the script after the script has been
  altered and applied with the script editor.
* Bumped version (1.0.0.svn13).
