more sensible resize and window settings.
lots of changes. See detailed commit info.

* Add some nodejs specific development stuff
    - jade template engine support
    - coffeescript support
        + set coffeescript indenting to 2 levels by default
    - stylus support
    - add node_moduls/** to wildignore so we don't get CommandT working
      on it etc.
* Better CSS3 support
* Replace all autocompletions with YouCompleteMe
    - Selecting of completions is restricted to the Down-arrow key since
      TAB will be used by UltiSnips
* Replace snipmate with UltiSnips, better in my opinion
* Use syntastic for syntax checking
* Replace vim-autoclose with delimitMate, since it is compatible with
  YouCompleteMe and works a lot better!
* Add EasyMotion - finally found a good use for this ;-)
