Test/case sensitivity

[jefscheepers]

I added a test to see whether AVU's are considered case-sensitive (which should happen with a case-sensitive database). This was tested:

• In our production environment (test passed)
• In a test environment with case-sensitive mysql (test passed)
• In a test environment with case-insensitive mysql (test fails as expected)

The test is ran last, so if it fails because the database is case-sensitive, the user will know that the rest of the tests still passed.

Also changed the README file to give the correct module name at Genius and Breniac.

I reduced the indentation and improved the test itself so it checks whether both AVU's have the appropriate value.

Thanks -- I now ran the tests myself and everything passed.
