Fontforge 20141014

Version bump & appropriate changes for the Fontforge formula. This is another considerable update and consequently a lot has been moved around, updated, dependencies shifted, and so on.

There may well be a bot issue with this update as Fontforge have decided to build a folder inside the bin folder, and the audit doesn’t like this.

```
 * Non-executables were installed to "/usr/local/Cellar/fontforge/20141014/bin".
The offending files are: /usr/local/Cellar/fontforge/20141014/bin/FontForgeInternal
```

Lilypond also receives a revision due to changes in the way Fontforge builds.
We didn't really follow semver before, it was just `2.0.DATE`... @adrientetar was against it prepending `2.0`, but @joescat did it for the previous release ([upstream discussion](https://github.com/fontforge/fontforge/issues/1797#issuecomment-59129730)).

Maybe the next release should be `2.1.0` and we'll start with semver from then on...
