Title: Compute PODS_ROOT Path relative to xcode project folder

This is just a start. I haven't verified this on my current project yet as the xcodeproject gem is choking on my project's plist values.

Any tips or ideas on how best to test this?

Summary of changes:

* `config` now has a `source_root` option that defaults to the `project_root`. If an argument is passed in to the install command, `source_root` will contain the directory of the project file specified.
* `PODS_ROOT` is now set to a path relative to the passed in project
* `PODS_ROOT` is now used everywhere instead of `SOURCE_ROOT`
