Building ligatures

[jens]

It would be great if there was a way to build ligatures similar to the accented letters syntax in the Add Glyphs dialog:

Agrave=A+grave@top

Perhaps something like this:

uniFB03=f_f_i

Ive been working for a while on a "glyph builder" thing

This will be a extension, I doubt if it would be embedded in RoboFont, since it's making design decisions.
