Server doesn't run with the server JRE

[mikehearn]

The problem is we depend on the JavaFX properties framework for observable properties and other things. We can do two solutions:

1. Include the JFX observables framework in the uber-JAR so they fill in the missing parts of the JRE. Involves a bit of fiddling to make such a modified jar.

2. Find some framework that does the same thing as what JFX is doing, but without the actual JFX dependency.
