playing around with fragmentation and mtus. added net_mtu to negotiate some mtu size for smaller (or larger) network messages. setting a custom mtu allows for message fragmentation too. trying to add a reworked deltaing protocol, including all sorts of fun stuff like bbox sizes, and higher ent limits. added support for content override entities. set the skin field to some (negative) contents value, and you get movable water with prediction and waterwarp and everything, though you likely want a custom qbsp or a shader to get backface culling. removed some madness with model skins, fixing some weird q3 bugs. fixed forced-pause-on-start for q2 fixed q3 server to actually accept client packets again. fixed strftime builtin git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@3979 fc73d0e0-1445-4013-8a0c-d673dee63da5
