Run tests on Linux, macOS, and Windows (#105)

* Try running tests on all three operating systems

* Try adding an MSVC build

* Make tests work on Windows

* Try reconfiguring Travis for this

* Maybe it's because we're in git bash

* Try explicitly doing something else for travis

* Remove a part I think is unnecessary

* Run the test EXEs as they compile
