Hello everyone,

As promised I've updated these patches. Just to reiterate, these are
David's patches. I've only changed a few things.

Here's the changes of the top of my head:
* First patch is unchanged.
* Renamed to dolphin-emu instead of dolphin-emulator since that seems
  like a more canonical name.
* Incorporated Björn's suggestions.
* Added a few more inputs to get rid of more externals.
* Enabled Qt interface.
