Build 5e96ddf

This marks the start of 64-bit support. Not extensively tested; report issues here.
Install instructions are unchanged (copy contents of package.tar.gz if running a Linux server, package.zip if Windows).

Note that this build may not work on 1.11 due to IPlayerManager interface differences.

If you are using a 32-bit server on SourceMod 1.11, download the previous release; there is no difference in functionality.
