selective font inclusion for emojis

Selectively include fonts for emojis that are used in the interface. This is done instead of including both the entirety of `NotoEmoji-Regular` and `emoji-icon-font`. This now requires the `pyftsubset` utility to be installed (under arch, this can be done with the package `python-fonttools`)
