bash/prompt: turns out, I broke it

I just noticed that the underline doesn't extend to wdroot anymore.
environ: opt in to freetype2 subpixel hinting (Arch)

Some of the Arch developers are really against enabling this by default,

makepkg: run under bash's `time`
git/config: add alias.emerge
ssh/config: add an alias for theos
ssh/config: remove some OpenSSH guards

ssh/config: remove automatic 'cluenet.org' suffix
ssh/config: reorder
