13.36 Regression tests

[Phil Holmes]

3 differences from .35 to .36 of note.

multiple-time-sig-settings.ly: I believe this is down to a re-write of the 
test file and fixing issue 1284.
utf-8.ly: differences in the horizontal spacing.  Probably not significant 
but might be worth checking by someone who understands what's happening 
there.
font-family-override.ly: the regression tester shows this as slightly 
different, but running .35 and .36 on my PC and comparing the output in 
Photoshop I can see no difference.

Summary: it looks like 1 critical regression fixed and no other problems 
revealed.
