fixing some issues related to initialization of the rich text editor.
resolves the issues related to Chrome or Firefox not working properly.

- added an initialization timeout timer so that if the initialization fails,
  we won't end up in a stuck state.
- cleaned up the adding pending command logic. we don't try and be smart and
  eliminate duplicate commands. the way that GWT attaches to the DOM and makes
  these calls makes it very difficult to handle.
