fix/edits to vector font handling

- don't overwrite the font path with "<builtin>" when the font file cant be found, it caused bad problems when loading files on someone elses systems when paths couldn't be found blender would silently clobber paths (tsk tsk).

- when fonts are freed their temp data is now freed too.

- assigning a new filepath to a font now refreshes the object data.
