Currently the extension install dialog shows permission warnings inside a multiline text field.

OAuth issues are different in that they are a list of issues, each of which can be expadned to show more details.

To support this I replaced the multiline text field with an NSOutlineView.

Screenshots:
  - OAuth issues + Warnings: http://i.imgur.com/Hbag3.png
  - Inline install + Warnings: http://i.imgur.com/gpLI9.png
  - Inline + No Warnings (outline view hidden): http://i.imgur.com/se9tH.png
  - Bundle install + Warnings: http://i.imgur.com/5H3Rm.png

XIB changes: Replaced warning and subtitle text field with outline view. Updated relevant outlets.
