Add terminus font

Latter is really generated from the former, but first is a regular text file
where changes can be viewed (if you understand encoding; TXT is better in this
case) and second is what is installed.

Note: you can use my bitmap fontpatcher to get exactly the same fonts as I have
saved glyphs in glyphs/{size}/{codepoint}: this directory was created as
I assumed that version of the glyph adjusted by me is suitable for any font with
the same font size.

This reverts commit 70b7e53ad9.

Closes #12.

Closes #9.

The glyphs that were added by fontpatcher.py were not positioned
correctly.  This was most noticable for the triangular separators. To
correct the glyphs I used the following modifications to fontpatcher.py:
- y_ratio *= 0.96
- y_diff += 300
The values are based on trial and error and what "looked" right, so
there is probably still room for improvement.

  set guifont=Menlo\ Regular\ for\ Powerline

Closes #1.
