Added a textarea control to the form for writing output to.  Added a
message writing system with a Observer-Observable so that messages can
be written to the form.  Converted most if not all outputs to use the
new logging system.  Added more logs to have better status updates.
Fixed the runButton action handler to not try to write mods to file if
the sort was a failure.  Added the JavaFX Maven Plugin and a batch file
for running it for building an executable JAR file.
