This reverts commit b37eacc1.

This reverts commit 807742d1.

We have now a must-use plugin which prevents Google Fonts from being loaded,
so these should not be necessary anymore (see #25).

I had messed up them, completely deleting the theme's functions.php file. This should fix #22.

not all of them apply cleaninly (sorry). See #15 and #5 for the list of things to fix.

the plugin has been abandoned, I have moved it to ai-mu-plugins for the moment.

Closes #17
