added :EX (colon-modified EX): exits SciTECO saving all modified buffers

 * this allows you to exit and save only those buffers that are modified.
   This was not yet possible using macros, since there is currently no way
   to query the dirty state of buffers programmatically.
 * even if there was, the necessary key presses might be too much for
   some users.
 * the ability to save all modified buffers has been explicitly requested
   by an user in ticket #4.
 * the new behaviour is not compatible with classic TECO where EX would
   save the current file by default but provides a relatively short way
   to do just that.
 * updated the documentation: there was also one mistake regarding the
   boolean that EX accepts non-colon-modified.
