ide/CodeEditor; ecere/gui/EditBox: Fixed CodeEditor/Designer issues caused by aa2c3d31c753e1b6e4e3000d9c3edd0371ae37c9 (trailing spaces nuking)
- Now doing this in the IDE CodeEditor instead
- Because this was done directly on the buffer, it would mess up several things including code locations and undo actions
- Editing with the designer or property/method sheets or auto complete safter a save trimming spaces would seriously mess up the code.
- Highlighted (red) spaces would not go away after going to the designer and come back prior to Save
