unittest added
Implemented rudimentary tests.

We need a testprojects folder and a /usr/local/share/mendix/ folder with
runtimes. The testprojects folder looks like this:

  testprojects
    4.3.2                   (version no., one for each test suite)
      m2ee.yaml.tmpl          (will be used as basis for m2ee.yaml)
      deployment              (the deployment folder from test project)
    4.3.3
      m2ee.yaml.templ ..... etc .....
unittests: print what failed if a test was unsuccessful
Use folder projects instead of testprojects, include a yaml file for reference

testprojects conflicted with tab completion
Added debugger testcase
Critical logs test added
