Don't need *two* older versions of libsbml!
Updates to the testing system.  
* New tests, and a way to test them.
* CMakeLists files updated to include new files, and to reference both .cpp and .h files, so they can be part of the project and therefore searchable.
* Add a way to point to the test files directory.
* Split FBC tests into their own test.
* Add commented-out way of outputting raw data for the sbml.org online validator.
* Better comments for various tests.
* Make test model reactions reversible (since they are).
CMakeLists files updated to include reference both .cpp and .h files, so they can be part of the project and therefore searchable.
Merge remote-tracking branch 'origin/develop' into sys-bio-testing

Python tester fixes:
* Changed amount/concentration Jacobian test to use the actual SBML file already imported, instead of importing a new one.
* Removed unused import
Make the jacobian model a real python test, and change the tester so that all a testing file needs is an SBML model and some tests.

Remove completely unused tests, and rename another one that's not yet ready to be tested.  Fix Test_1 so that the 'species concentrations' test is actually working (the '[S1]' format made it think it was a new test.)
SBML Test Suite tests that now pass re-added.
'TestModel' updated to allow the user to set a path to the test files, to allow tests to be skipped, and to be less stringent on accuracy of data comparisons.
Update CMakeLists.txt

Fix name of file.
Update Suite_SBML_Tests.cpp

Move tests we now pass.
Report to the user for all tests, not just some.

bump version to 1.2.6 final, update news, warn about comp extension
Fixing the memory leaks in gillespieMeanOnGrid and gillespieMeanSDOnGrid
Rename the tests 'rrtest' and update to a format that will work with both the C and Python testers.
Update Python and C test runners to work with new hybrid format of rrtests.
Allow ini file to read XML files; allow the section file to store whether or not it was used in a test or not.
Move (and slightly change) the jacobian test from the Python directory.
