Pull'd develop branch

* Bump JDA version to 324 (#31)

Updates JDA (they forgot something with slash-commands, has been added now)

* Add spotless integration

This hopefully makes formatting more consistent. The Eclipse XML style
was chosen as it is understood by Eclipse, VSC (JDT), Spotless and
mostly by IntelliJ.

* Make gradelew executable

* Add "Remove unused imports" setting to spotless
