refactor(nixos): bring back htop; remove glances, urxvt, xcape

Glances is just a bit too slow, especially compared to htop. Going to
have to find a way to monitor network bandwidth (glances monitoring for
it was a bit too rudimentary anyway, I think). Probably going to be
either ifstat, nload or nbwmon (if I can get the latter packaged).

I think I'm just going to use caps2esc (interception-tools) instead of
xcape. Therefore, no need for urxvt since st isn't buggy with caps2esc!
:D
