Add zlib support to the web build, to make running the rerelease's content feasable with a hack to get png files sized right. Enable botlib in web builds, now that q3's data can be used. Fix up our webrtc support a little. Enable the server browser in web builds (rtc hosts only, for now). A couple of related minor tweaks. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@6088 fc73d0e0-1445-4013-8a0c-d673dee63da5
