* Started using the static keyword in a few more places in the client
* Updated libpng, libmpg123, and freetype to the latest versions, with position-independent code turned off rather than set to "both"
* 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.
Added BMP (24-bit uncompressed, 8-bit uncompressed, and RLE8) and PNG support to File::ReadImageFile(). So far everything in FileHandler is presumed to be safe with any input file except UTK decompression.
Also started making use of the static keyword in various places to aid the compiler in optimization.
