* allow telling cmake where to find required fonts in system when user supplies the paths, as suggested by unC0Rr, e.g. -DFONTS_DIRS='/usr/share/fonts/truetype/wqy;/usr/share/fonts/truetype/dejavu' * the build system will use the paths to lookup fonts and install those not found * the engine will load the paths into physfs (mountpoint /Fonts) to make the fonts available at runtime * overriding fonts in packages should be possible again now

allow engine to use symlinked fonts. disallow packages to "overwrite" fonts
