Closes #850

* lib-subcommand:
  Add Pod lib command #850

Closes #1063

* 'master' of https://github.com/ashtom/CocoaPods:
  Use cp instead of rsync to copy frameworks (refs #1063).

- This also fixes a bug which lead CocoaPods to always use the
  aggressive cache.

Closes #1160

Closes #1157

See #1152

fix for erroneous linting on 0.21.0.rc1

- let spec in "validates a podspec with dependencies" validate
- fixed a bug in `write_podspec`

Add mkdir command to make sure the folder Contents/Frameworks exists (otherwise the first framework becomes this folder).
Change rsync command to cp to keep the file structure and all symbolic links.
