Updated readme to use "tpope/vim-rails.git" repository.

- closes #64

- closes #104

- closes #110

- TODO: crashes `vim -g -u test/vimrc`

Also save/restore input so potential mappings aren't broken.

Prevents the user from having to type a space before the search term.

- closes #80

Added my Vim config link (which makes heavy use of Vundle)

Also renamed the "Examples" section to "People Using Vundle"

Update vundle.vim version to 0.9

- use `redraw` instead `redraw!`
- closes #90

- for testing purposes

- to avoid accidental removal

- so it better reflects the content

- do not clutter up ~/

- installer is verbose enough to signal errors

- to avod error when deleting nonexisting buffer
