Avoid conflicts with unpatched Terminus

The file names currently in use conflict with the non-patched version of
the font on Arch Linux. This commit renames the files and updates the
fonts.dir to avoid this conflict.

add fonts.scale and fonts.dir files for `xset +fp`

The fonts.scale files were generated by running `mkfontscale ./**/` and
the fonts.dir files were generated by running `mkfontdir ./**/` in this
Git repository's working tree.  Run those commands again to regenerate.

These generated files let you register their corresponding True Type
fonts with the `xset +fp` command, which "installs" them under Linux.
For example, you would do this by running the following commands if you
cloned this Git repository to your ~/.fonts/powerline-fonts/ directory:

xset +fp ~/.fonts/powerline-fonts/AnonymousPro
xset +fp ~/.fonts/powerline-fonts/DejaVuSansMono
xset +fp ~/.fonts/powerline-fonts/DroidSansMono
xset +fp ~/.fonts/powerline-fonts/InconsolataDz
xset +fp ~/.fonts/powerline-fonts/Inconsolata
xset +fp ~/.fonts/powerline-fonts/LiberationMono
xset +fp ~/.fonts/powerline-fonts/Meslo
xset +fp ~/.fonts/powerline-fonts/SourceCodePro
xset +fp ~/.fonts/powerline-fonts/Terminus/BDF
xset +fp ~/.fonts/powerline-fonts/Terminus/PCF
xset +fp ~/.fonts/powerline-fonts/UbuntuMono
xset fp rehash

Saving someone the hour I just wasted before stumbling upon this issue.

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.

Add Liberation Mono Font

Fix typo

Include Menlo bold/italic. Fixes #25

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.
