Set up continuous integration testing

[Pharmhaus-2]

In Mungo, the code is not covered by tests, but somehow you need to test it. You can configure the Continuous Integration server, which after each commit will do the following:

 Build the Mungo distribution, i.e. compiler, documentation, Jentos IDE and more. Even under Linux, it does not matter - this is just a test.
 Compile all samples from samples for at least HTML5.

And in the future, it will be possible to add full-fledged unit tests for the compiler and API separately.
