Add basic support for font command and add convenience access to fonts

[Kolaru]

Fix #21 and #23.

Support for \mathrm, \mathit and \mathbf.

Also export get_font([family], fontstyle) -> font_object::FTFont and get_fontpath([family], fontstyle) -> path for easy access to the fonts from the outside world.

@knuesel I'm interested by your opinion on the latter, before merging.

My opinion FWIW is that convenience functions are great, but shouldn't hold up an important merge that affects all user plots. I know I'm impatient (sorry!) but could this be split so we don't have to wait?

[knuesel]

@Kolaru this looks great! (I'm on vacation without computer so can't look at the details but based on your description it looks perfect to me)

@knuesel Thanks for the quick feedback. We are still pre 1.0 so this can be changed without fuss latter as well :)
