add custom font support for all client ui

Browse Source 
- new FrosFont renderer: loads ttf/otf from fros/fonts/, rasterizes
  text to cached textures, falls back to the vanilla font when unset
- Font/FontSize settings in ClickGui (fontSize only shows when a font
  is set); missing files retry automatically every 2s
- all gui buttons, panels and hud modules now render through it
- handles section codes and styled components (watermark accent color)
