If the Bundle is hosted on GitHub include link to compare the commit range
visually on GitHub.

Keeps track of the current commit with a vundle_update tag before
perfoming an update and adds all commits pulled in the update to a
Changelog accessible via pressing 'u' after BundleInstall! completes.

Link to vimified conf in README

Thanks!

- closes #141

- also work in batches

- having it as a function makes it slower

change setup url to use HTTPS instead HTTP

Added .gitignore file so as to play nicely as a git submodule.

- as `http` one just redirects to `https` on GitHub

- use `let g:vundle_default_git_proto = 'git'` to set default protocol
to build URIs to clone from

- "transcient bundle" - a bundle installed with :BundleInstall or interactively
  without being declared in .vimrc

- treat them the as if they were configured
- so everything works the same

- ie before this change helptags weren't generated automatically
  with `BundleInstall bundle` or with interactive mode

- it changes the way `:BundleClean` works, since it removes directories
  that aren't bundles
- FIX: `:source .vimrc` to let `:BundleClean` remove transcient bundles

- closes #99

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"
