Linux dedicated server crash

[ray]

The hacky fix to get x86 Linux to build in #124 doesn't work and makes it crash.

The x64 dedicated server also doesn't work, possibly due to mixed 32/64 binaries, where Valve server binaries are preferring the _srv.so and we aren't.

We'll need to fix the build process for x64 and/or possibly ship modified engine binaries like 0.5 did.

[ray]

64-bit fix is to build with /dedicated, will work on the build script in the next few days.

We need to copy:
lib/public/linux64/libtier0_srv.so
lib/public/linux64/libvstdlib_srv.so
lib/public/linux64/bitmap_srv.a
lib/public/linux64/choreoobjects_srv.a
lib/public/linux64/dmxloader_srv.a
lib/public/linux64/particles_srv.a
lib/public/linux64/tier2_srv.a
lib/public/linux64/tier3_srv.a
lib/public/linux64/vtf_srv.a

Still gives some errors loading steamclient.so but doesn't crash anymore. Not sure if that's just my environment - neither HL2MP or TF2 ship with a 64-bit steamclient.so, and error goes away if I copy one into the folder it's looking for.
Need to look into that, we might just ship one to be sure.
