added globbing command EN

 * implements the same globbing as the EB command already did
 * uses Globber helper class that behaves more like UNIX glob().
   glib only has a glob-style pattern matcher.
 * The Globber class may be extended later to provide more
   UNIX-like globbing.
 * lexer.tes has been updated to make use of globbing.
   Now, lexers can be automatically loaded and registered at
   startup. To install a new lexer, it's sufficient to copy
   a file to the lexers/ directory.
