Merge pull request #342 from deepy/master

Added GUID to score printout.
Decoupled viewmodel FOV from view FOV. Added option to not lower viewmodel at high FOV values. Defaults to inheriting view FOV and lowering viewmodel like base.
Fixed several instances in g_nav.c where it checked for only the first client (instead of all of them, like it was intended to)
Another case of the client number fails: saber locking checks only treat client 0 as an actual player
Whoops, minor mistake on my end. Was checking > 0 instead of >= 0.
If custom skin is set to model_default for all 3 parts, just use /model_default.skin in SP.
Fixes issue with dfmod and possibly others.
Unused function relating to key events in unix backend.
Fixed possible major issue with unix input code. IN_Frame was being called more than once. (Once in main per-frame, and once in every event call)
Missed a reference to unused function.
