Started to add unit tests.

Refactored IntegerArrayList, which is now not needed anymore (who implemented this in the first place?)
Auto-Formatted DPointSetMultiIcon -> it was just so badly formatted I had to do auto formatting to make it readable.

Added test for eva2.tools.StringTools (partly at least)
