Example:
http://openeye.openmods.info/crashes/f1cba015759d6b49c8e45c8b2c60cfde

Notice codechicken.lib.vec.BlockCoord@ffffec05
The @ffffec05 should be stripped, not just from the first line, but from all class definitions. Otherwise the SHA is different each time and there becomes many 'unique' crashes that are the same.

Though I would like to implement that as server rule, since client-side ones should probably be reserved just for sensitive information. Rules on server can be easily changed and allow filtering data from previous versions.

This is done as a quick fix server side - although I intend to tidy it all up at some point.
