* packer: +warnings on implicitMaps, mapNoComps
* packer: known problem: minizip crash, when trying to get file with 2039 year date from disk
* -repack: repacks multiple maps, strips out only required shaders; main argument is single bsp path or txt with full pathes to bsps
switches: -dbg: talkative mode; -png: include pngs, at highest priority; -complevel: -1..10, def 0, compression level
uses additional exclusions file repack.exclude with different logic
* packer: rewrote logic to make sure not to include excluded stuff
* packer: preserves file date, if grabbing file from .pk3 too
* packer: in case of missing *ingame* resources pk3 gets _FAILEDpack suffix
* -pk3: autopackager mode(complete Q3 support); bsp path as input; switches: -dbg - talkative mode, -png - include pngs, at highest priority
is using file 'gamename.exclude' to exclude vanilla game resources
tip: ioq3, netradiant, compiler (and packager) treat *.pk3dir directories as separate pk3 files
