fteqw/plugins/jabber/sift.c
Spoike f08489f141 .po support for qc. 
rewrote messagemode to support utf8 properly, as well as left-arrow etc keys.
support for mouse-over images on console links and stuff.
added r_lerpmuzzlehack for certain viewmodels.
use libtool's dlopen stuff on cygwin to try to cover some cygwin path differences.
try to support utf-8 in filenames even in windows (only in nt, 9x is still ascii only).
added certificate validation for gnutls. gnutls now enabled by default in linux.
d3d11 tweaks. shadowmapping works.
tweaks for updated terrain format, to try to fix some inefficiencies/limitations.
xmpp plugin can now display avatars (xmpp /set avatars 1)
xmpp file transfers supported by default, but capability is disabled by default (can be enabled by hacking config).
