Create a Linux install for Raintale

[shawnmjones]

This script should take into account the lessons learned from #19, #20, and #21.

Ideally, we would create an RPM install for RedHat-based systems and a DEB install for Debian-based systems, but that may be a bit too much to test for the duration of the IIPC Grant. A tarball containing the necessary files and an installation script is likely enough. To make it administrator-friendly, we could apply Makeself as well. This way the user can download a single file, execute it, and it will extract our content, execute our script, and start up the Raintale GUI.

An alternative to Makeself is pyinstaller. This Stack Overflow discussion and this discussion may help us apply pyinstaller to this Django application. The benefit to using pyinstaller is that it may help us eventually make Raintale available on Microsoft Windows.

We will discuss this at our next weekly meeting @himarshaj.

Based on our conversation during Monday's meeting, it appears that Docker is probably best because it provides a stable environment from which to manage dependencies.

These were all included in the main branch as part of pull request #40.
