Fix plPythonPack Logic
PhysX conversion code validation at compile-time

Seriously? Offsetof has been around for a long time, and eap added a
compiler_assert for his crazy netcode. There's no excuse for that to be
happening at runtime.

plPXConvert::Validate to compile time
Only validate FixedKeys in debug builds
OpProgress: only skip space if we drew something
StringStream means less recursive sprintf...
Ensure there is always book-spinning while linking

This should help people realize that things are happening... Even if
whatever server they're connected to takes a very long time to process a
join request. At some point in the future, the linking process should be
de-serialized.
MOULa is now Build 918
Another decimal place in the profiling display

And Hoikas said, "I cannot tell a difference in the skinning times on my
not-crappy computer with only a tenth of a millisecond resolution." So we
now have hundredth of a millisecond in the profiling display. These are
the kinds of problems you have when developing with a machine that doesn't
suck. It would be nice if players didn't try to run the game on machines
from before the exctinction event that ended the Permian era.
