Add per-profile disk caching of complied GPU shaders.
This CL adds a per-profile disk cache for any shaders that are
complied while using the profile. When the profile is first opened
the shaders will be loaded from disk and used to pre-populate the
GPU memory shader cache.
The disk cache takes the load time for From Dust from ~30 seconds
to ~18 seconds on my Linux machine for any loads after the first.
