[sldev] Optimizing load time.

[James Cook]

The MD5 calls may be something as dumb as repeatedly MD5-ing the 
password every frame at the login screen.

These options speed up startup time for developers:

-noaudio
Skip audio library initialization, which on Windows takes a couple seconds

-noquicktime
Skip QuickTime initialization, which takes several seconds due to DLL 
loading.

-nopreload
Skip UI texture decompression, makes buttons look wonky for a while but 
saves a few seconds

-noprobe
Skips DirectX hardware probe to determine available VRAM.  Causes VRAM 
setting to default to 512 MB but that doesn't matter for simple scenes.
