Dustmod zsh theme

Started with fixes, improvements and modifications to the simple and clean dst (code) theme. In the end it became yet another fully featured zsh theme. Still striving for cleanliness, though!
Picked inspirations and features from various themes: avit, bureau, clean, dst, jreese, mortalscumbag, michelebologna, sunaku, sunrise, tjkirch, spaceship, pure

Features are:

• Solarized color-scheme inspired theme with info and command prompt split on 2 lines to allow for enough space for both
• clock/time on the right
• the usual: username, host, current directory in prompt
• different color and prompt for root user
• show a little ✗ in front of the current path if it is not writable by the user
• show if on ssh connection
• git status if inside a repo: shows the branch-name and repository status in a verbose description or using only symbols (✓✶✗↝✩⇡⇣↱⤱)
• python virtual environment name in prompt
• show return code of last command if it was not 0. additionally translates the return code to a human readable error message
• duration of last command for long running commands, i.e. > 20 seconds
