zsh: merge environ-leeloo into profile-leeloo
zshrc: source zshrc-hostname instead of environ-hostname
htop: sort by RES
profile: moved XAUTHORITY to -leeloo, export GPG_AGENT_INFO properly
penta/chrome.css: reindent, remove tab being full-width

The full-width thing had a bug where tabs ended up in weird places with
gaps between them when you closed old tabs.

This fixes errors from git when in a repo without any commits.
