First attempt at caching tangents meshes
Moved SFXStatus enum to SFXBase.
Removed debug output.
Avoid calling querying the openal status in getStatus (which causes
a slowdown of sfx).
Fixed compiler warning.
escape or back on friends profile takes you to your profile

Also, fixed bug where user info dialog was accessing m_enter_profile
after it was deleted
Add volume, speed, and position settings to be done by the sfx
thread. Removed more unnecessary error checks (which mostly flood
stdout with 'not playing ...' messages), and renamed volume, position
and speed to setVolume, setPosition and setSpeed.
Merge branch 'master' of github.com:supertuxkart/stk-code
Fixed #1622 (missing password field in login screen).

Cleaner fix for #1626, closes #1626
Improve situation of #1624 - it should only happen now if you pause the
game in the first one or two seconds after start (still wip).
Handle the setting of the listener position in the  sfx thread.

Run the music manager from the sfx thread.
