Porting unit tests

[Jacob Carlborg]

I recently noticed that the SWT repository contains unit tests. I think 
it would be create if these tests could be ported and included into DWT.

The tests are located in the "tests" directory in the SWT git repository:

http://git.eclipse.org/c/platform/eclipse.platform.swt.git/tree/tests/org.eclipse.swt.tests?id=v3449

The address of the git repository is:

http://git.eclipse.org/gitroot/platform/eclipse.platform.swt.git

We're using release 3.449.0, with the corresponding git tag v3449.
