Pod push, pod spec lint, and minor changes

* master:
  correct typo
  add functional spec for http downloader
  refactor: raise a UnsupportedFileTypeError when unexpected file type is given
  cleanup http downloader, add spec
  load yaml only when needed
  add http downloader - that download repo with http and then decompress them
  Travis build status only for master branch
  Small cleanup.
  Removed broken Xcodeproj bundle install command from rake bootstrap task

- renamed --no-build option to --quick, simplified options handling
- simplified initialization
- removed repo check for license warning
- minor cleaning

* 'pod-push' of github.com:CocoaPods/CocoaPods:
  Fix spelling error and print build output from `spec lint` when in verbose mode.
  Allow both the name of a pod _and_ a github url to be specified.

- the arrow is yellow/red according to the type
- Nno needs of other types as the messages should be  clear enought

This ensures the name of a pods will be properly cased in cases where
the url does not contain it.

This is simply hacked in, it needs some proper looking over.
