Do not load unnecessary VPPs in dedicated server mode

Following VPPs will no longer be loaded:
- audio.vpp
- maps_*.vpp
- levels[123].vpp
- maps[1234].vpp
- music.vpp
- ui.vpp
- dashfaction.vpp

Also don't check if sound files exist in dedicated server mode.
This change may slightly speed up server startup and reduce number of
logged errors in minimal setups.
