Approved version of FontForge
It appears - though some caution is still called for because I haven't tested this carefully - that FontForge has improved enough that Tsukurimashou can now be compiled with the mainline version, local mods not necessary. Yay!
Figure out exactly what needs to be fixed in "stock" FontForge to make it work with Tsukurimashou, and do at least one of:
* Convince the FontForge people to clean up their own mess in the main distributed version * Solidly document how our users can fix their local FontForge * Fork FontForge and distribute a "really works" version to our users
