Title: Use special variables where we can

This pull request changes the following:

- `whoami` calls for `$USER`
- `pwd` calls for `$PWD`
- `hostname` calls for `$HOST` or `$SHORT_HOST` where it suits (`$SHORT_HOST` is defined in `oh-my-zsh.sh` script.

This allows for less processes spawned and a more consistent codebase.
