Remove StarterKit completely, because it is obsolete

This fixes issue #372.

I took a close look at the code and found that
- it depends on classes and members no longer present in CppUTest
- it appears to implement functionality that has been superseded by current CppUTest, such as early test exit and memory leak warnings.

After removing those, nothing meaningful is left anymore.

I propose removal of these files, because they cannot be compiled and might create confusion.
