Added bundle 'tpope/vim-eunuch.git'

https://github.com/tpope/vim-eunuch
Vim sugar for the UNIX shell commands that need it the most. Features include:

    :Unlink: Delete a buffer and the file on disk simultaneously.
    :Remove: Like :Unlink, but doesn't require a neckbeard.
    :Move: Rename a buffer and the file on disk simultaneously.
    :Chmod: Change the permissions of the current file.
    :Mkdir: Create a directory, defaulting to the parent of the current file.
    :Find: Run find and load the results into the quickfix list.
    :Locate: Run locate and load the results into the quickfix list.
    :Wall: Write every open window. Handy for kicking off tools like guard.
    :SudoWrite: Write a privileged file with sudo.
    :SudoEdit: Edit a privileged file with sudo.
    File type detection for sudo -e is based on original file name.
    New files created with a shebang line are automatically made executable.
