Makes FontData importable resource.

Adds multi-channel SDF font texture generation and rendering support.
Adds per-font oversampling support.
Adds FontData import plugins (for dynamic fonts, BMFonts and monospaced image fonts), font texture cache pre-generation and loading.
Adds BMFont binary format and outline support.
