* Condensed STR# reading of formats 0, -1, -2, and -4 together. * The STR# parser now supports "formatless" format 0 STR# chunks. * Made all of the command-line tools cross-platform; replaced file IO with fopen()/etc, and replaced time measurement with clock(). There is no longer a dependency on Windows.h. * Added a "Server GUI" folder to tools. Niotso Server will basically be a background daemon., and communication would "normally" be through the command line until you run a GUI.
