Emit table GDEF with GlyphClassDef and LigatureCaretByPos statements

See original GitHub issue

When glyphsLib produces UFO for a font with ligature caret positions, the generated features.fea should contain a table GDEF block with LigatureCaretByPos statements. Originally, I planned doing this in ufo2ft but that seems the wrong place; see also https://github.com/googlei18n/ufo2ft/issues/91.

Here’s the logic of Glyphs.app, summarizing a discussion thread on this bug for reference:

Base: any glyph that has an attaching anchor, and that is neither classified as Ligature nor Mark using the definitions below;
Ligature: if subCategory is “Ligature” and the glyph has at least one attachment anchor;
Mark: if category is “Mark” and subCategory is either “Nonspacing” or “Spacing Combining”;
Compound: never assigned by Glyphs.app.

Guess we can close this. Please file another bug (with a concrete example) if I’m wrong.
