first batch of real unit tests (#45)

* move things around for better compatibility

* switch back to SWIG JSE current

* fix and test most of the basic CRS features

* basic CoordinateOperation tests

* retrieve the SWIG output when testing

* make a debug macro

* skip the crashing test

* drop unintended change

* emscripten is going a little bit too far

* use hash codes for the downcasting table

* obviously it is evaluated, why it wouldn't be?

* run all tests in the browser

* no need for two quickstarts in the browser

* use a proper name for this battery

* use forward slashes on Windows
