New small font & Bug Fixing

This adds the extended small 6x8 font (#173 / #176 )
Improves a few translations
Fixes the memory bug where I had accidentally located the settings table 8K too early in flash. This was causing weird bugs in fonts/calibrations/settings.

This does mean you will need to re-generate the bootup logo HEX file for those of you who use them.
The python script is already updated, and a new GUI C# app is included below.
