Spoike 9aed521689 make developer a little less spammy. move much of it to developer 2. 
net_mtu "" now means something large for servers and something smaller for clients. this should give clients more freedom to screw up their connections as much as they want when servers are not configured. I dunno.
package manager now tries to include packages listed from default.fmf. note that this may include dlls etc so this isn't available for any other fmf (ie: ones specified via the commandline/file associations).
fix up trace logic to use skeletal data for skeletal models, finally fixing toneddu's big hitmodel crash. hopefully.
console links inherit background text colours, where possible.
fix text background colour weirdness for both freetype2 fonts and spaces.
qcc: implement support for mac line endings, matching scintilla's line numbers, although this breaks rogue due to stray carrage returns inside a single-line comment (easy to fix, assuming some scintilla-based editor, anyway).
server: reworked deltas overflow to do round-robin properly with priority for players, so things shouldn't stall when overloaded.

if we're loading for the fallback then we're loading this data for quake compatibility,
so we grab only the first 4 rows of each set of chars (128 low chars, 128 high chars).
if we're loading a proper charset, then we load only the first set of chars, we can recolour the rest anyway (com_parseutf8 will do so anyway).
as a final note, parsing iso8859-1 french/german/etc as utf8 will generally result in decoding errors which can gracefully revert to 8859-1 safely. If this premise fails too much, we can always change the parser for different charsets - the engine always uses unicode and thus 8859-1 internally.
