Spoike 5d2ff1286d first version with dtls support. disabled for now.
schannel (ie: windows native) works as a client, not a server.
gnutls provides both client+server support. servers need to load a pre-generated cert from disk.
tweaked gamepads to actually work in the web target.
tweak gamepads a bit. added gp_* bind aliases. xinput+sdl+web should all use the same key mappings.
finally added the itemtimer glsl.
tweaked software renderer to not be quite so buggy, but you probably won't realise that if you try it.
disabled the ill-fated QWOVERQ3 feature.
don't do the oldorigin thing in quakeworld mods. hopefully this'll fix cspree's weird stuck-in-floor issue.
dpp7 is buggy serverside. disabled for now. I'm part way through rewriting its deltas.
