Everywhere: Make loading pcx format possible

[tetektoza]

Currently WIP, I only need to figure out more error handling and how to handle loading/saving the existing palette which is at the end of PCX file.

Nice, will be nice to have all file formats used by the game covered, even if pcx is a common format it's support is starting to be phased out by a lot of other image tools. The only thing missing then will be the .bin that specifics the frame width for pcx fonts.

They're .txt these days, with a frame width per line, relevant issue #22

Well not the original assets which is what I'm referring to :) Some one actually asked if there was a way to convert the original font and this would make that A LOT easier. I would say supporting the .txt format is less important as the build process generates .clx which d1gt already handles.
