Notable changes:
- Fixed a memory leak the size of the gamedll when extracting a missing
gamedll from the cache file on Windows Steam servers. Found by Wei
Mingzhi.

Pirates, Vikings and Knights Beta 2.1.
- Added more entities for Sven Coop 3.0, Vampire Slayer "Chapter VI",
Earth Special Forces Beta 1.2, Science & Industry 1.0.
- Improved parsing of plugins.ini file to not report errors on empty lines
and commented out lines that start with whitespace.
- Added support for loading AMD64 games (Linux game dso needs to end in
"_amd64.so" instead of "_i386.so") in AMD64 Metamod version.
- Added "lin32" and "lin64" keywords in addition to "linux" keyword for
plugins.ini file to support using the same file for the same game on
both 32bit and 64bit servers. The "lin32" and "lin64" keywords override
the "linux" keyword when used on the same plugin. Do not use "linux"
when using "lin32" and/or "lin64" keywords for the same plugin.
