Fixed issue with music tracks not playing.

In gameplay mode when one music track finishes the next one did not
start automatically. This was resolved by loading music with FMod's
FMOD_ACCURATETIME flag that will scans .IT file first and create a seek
table for FMOD_Channel_SetPosition() to work.
Removed redundant CSounds method.
Changes in syntax and comments.
Game balance changes.

Change: Landmine damage increased from 35 to 60
Change: Maximum anger increased from 130 to 200
Change: Damage formulae adds 100/damage to anger. This gives a bonus to
vehicles that deal less damage.
