enhancements to pear-core tests

Hi Ladies and Gentlemen: I just pushed a bunch of changes to the test suite that enable the test suite to be called from anywhere properly run against a git repository / working directory. Prior to this, several tests failed if called from the main repository directory due to include path issues, so the tests had to be run "tests" directory. That caused include statements to not find the files in the local repository and then go to the installed PEAR files. The result was developers ended up not really testing the changes they were making.
