General Improvements + FreeBSD Fixes (#15)

* Remove Thunderbird and Audacity. Don't add Geary to new installs but don't remove it in case it comes with the distro.

* Remove Thunderbird from Favorites.

* Add more systems to Dev branch.

* Add sudo so older distros don't ask for password on every app update.

* Alias for sync to help save some time typing.

* Post less often to hopefully allow keeping up a year of data in less than 16GB.

* Allow workstations to use printers without manual intervention.

* Section does more than UI work.

* Fix file path.

* Upgrade nanominer to 3.3.13.

* Add more chances for script to automatically restart.

* Add the minhashrate for x570.

* Up the minimum for x570.

* Fix "1: syntax error, unexpected USERGROUP, expecting END or ':' or '\n'" on FreeBSD.

* Correct FreeBSD package manager.
```
ansible -m setup localhost | grep ansible_pkg_mgr
        "ansible_pkg_mgr": "pkgng"
```

* Set vi as EDITOR.

* Add FreeBSD to distros that include make. It does not have an install from pkg.

* Make on FreeBSD hates dash-to-dock's Makefile. GMake has better luck.

* Update supported OS's.
