Revision 1432134

- fixed a typo in the ASBlockWalker ('switch' instead of 'swtich')
- fixed issue where there always are two extra line breaks at the end of the output
- fixed issue where there was a line break to many in the 'header' if there are no imports
- cleaned up all tests:
    - all asserts are now commented in: if test fails, it's given @Ignore and a TODO
    - all @Ignore tests now have a TODO or at least a comment
- made a few more tests pass
