core/utils.py:  The `minify()` function will now only attempt to minify files that don't end in 'min.js' or 'min.css'.
app_terminal.py:  The `TerminalApplication.new_terminal()` method now falls back to defaults if no 'term', 'rows', or 'columns' are given.
Themes:  Lots of tweaks all over the place.
SSH Plugin:  The editor is now enabled on the Known Hosts textarea.
SSH Plugin:  Saving the Known Hosts now works properly in Python 3 (it was throwing an exception in regards to 'must be str not bytes').
Editor Plugin:  It no longer throws an exception if no callback is given to either the `GateOne.Editor.fromTextArea()` or `GateOne.Editor.newEditor()` functions.
