Adding gitignore and a default vimrc.

You MUST rename or symlink the vimrc elswhere in order to use it.
Adding pathogen.

- Updated pathogen infection path in default vimrc.
  - AFAIK the braces allow pathogen to sniff all the folders under `~/.vim/`
Adding tagbar.

- Press F8 to enable it.
- Had to update the pathogen#infect() path to empty.
  Now it loads plugins correctly.
Adding tagbar-phpctags.

- Allows tagbar to build a searchable window from PHP tags.
Adding nerdtree.

- Makes browsing the filesystem much easier.
Adding nerdcommenter.

- Makes adding docblocks and related indentation a bazillion times easier.
Renamed vimrc to vimrc.dist

- Just a friendly reminder that this might not be the file of choice for everyone to use.
Not sure why the last commit didn't catch this, but ...
Fixing php-ctags path.

Forgot to create the symlink before.
- IMPORTANT:
  - The phpctags file is not executable by default.
    The submodule will be marked dirty by git if you modify it.
  - The original repository is found at: https://github.com/vim-php/tagbar-phpctags.vim
  - The repository I selected has the phpctags script already built for *nix systems.
