Use aliases on the JAR, more changes and the v2.2.16-beta2

- Don't create aliases-english.sk and aliases-german.sk by default, use ones in the JAR
to keep updated

- Added colored loaded script message based on load times, you can enable with a system
property, not tested though

- Added a new NonReflectiveAddon interface for speeding up the getFile method. Only a
very very small enhancement.

- Added assertions for closeOnEnable and disable, also fixed the version error and added
load times of aliases, language files etc. in debug verbosity.
