Interlinear gloss tweaks

[nschneid]

They're looking great! Just a couple things:

• [x] <br> is displaying on the server: http://flat.nert.georgetown.edu/he/%D7%9C/ I double-checked that base.py includes it in the whitelist. Any idea what might be going on?

• [x] Could you add the CSS class example alongside interlinear?

<br> is fed as an argument to the macro, so it's being html escaped, right? Is there a way around this?

Is it possible only to escape the parts inside {...}? Maybe by tweaking https://github.com/nert-gu/Xposition/pull/129/files#diff-53ef184a129d8b895c218d8070b610f4R251?

Try this.

Voilà!
