fast Dolphin version is online

Can't be merged automatically, probably due to two tiny changes in *scriptmodules/emulators.shinc*

The new dolphin version is [based on the Hunter-Kaller PPA](https://github.com/beaumanvienna/RetroRig/blob/Ubuntu-14.04-Beta/supplemental/build-dolphin-emu-ppa.sh#L98). The dual-head changes are [applied by patches](https://github.com/beaumanvienna/RetroRig/blob/Ubuntu-14.04-Beta/supplemental/build-dolphin-emu-ppa.sh#L119).

It is fast as hell ( :dash: ) and plays very beautiful games ( :dancers: ).

This pull request should close #112 "Dolphin slower (not sure since when)" .

Issues #80 "Sound driver sometimes crashes when usign load/save state (Dolphin)" and
issue #88 "Dolphin (Gamecube) Incorrectly renders in fullscreen" are obsolete and can be closed as well, when confirmed.
