Update Anonymous Pro

[why]
We use a prepatched font not the original Anonymous Pro.
The prepatched font contains no bitmaps and is thus like
Anonymous Pro Minus. Also some font internals that fontforge does not
copy out of the box are differing.

And we miss the Bold and Italic variants.

[how]
Crossgrade to original Anonymous Pro as source and add the missing
weight/style.

Add Anonymous to SIL.
Handle 'Pro' naming parts (do not detect 'r' as short for 'Regular').
