Dolphin packaged

Good news everyone! Dolphin is online in our PPA at:

https://launchpad.net/~beauman/+archive/ubuntu/retrorig/+packages

In addition, I've uploaded the build outputs to our Box-box.

Dolphin is now compiled against wx3.0. I had to upload another package to the PPA, polarssl, with version 1.2.8. This is because I didn't figure out how to compile dolphin against the recent polarssl package available in the official Ubuntu repositories. Futhermore, I had to add a new dependency to our PPA. It now also depends on https://launchpad.net/~glennric/+archive/ubuntu/dolphin-emu, mainly for the package  `miniupnpc`.

Any kind of testing is appreciated, especially regarding issues 

* Dolphin (Gamecube) Incorrectly renders in fullscreen #88
* Sound driver sometimes crashes when usign load/save state (Dolphin) #80

After a simple `sudo apt-get update` it should be available for installation with version 2:4.0.2.0
(where 4.0.2 is the Github tagged version, .0 states our patch level or unpatched in this case. The 2: in the beginning just makes sure the package is superseding any other official package available).
