Add freetype to build and implement GfxAnimation loading

Integrated freetype into the Makefile build process and updated related clean/help targets. Added static animation loading and caching to GfxAnimation, including initial SMD file parsing logic in model.cpp. Updated .gitignore and project configuration files accordingly.
