Don't regulate Framerate on Pandora

Restrict the Eps precision change only to Pandora platform
fix Inverted Right and Middle button on certain case with SDL
Added some Failsafe. Fixed a crash in the new game intro cinematic (when Boss of TFE die and Sam goes to the UFO) on the Pandora
Some Pandora fine-tunning
Tried some asynchronus input method, but doesn't seems to works
