- removed the dependency on exuberant ctags which parsed the python source code wrongly anyways. From now on only VIM with python support is needed. This might greatly help windoze users.
- fixed problem with parsing ctags output on python files that use tabs
- when there is a syntax error in the file and ctags parses it incorrectly a warning is displayed in the command line
- fixed problem with undefined window-bound variable w:PHStatusLine when a window has been split into two.
- unbound event BufWinEnter because it's not needed because of the above change now
