[GRASS5] GRASS test suite update

[Sören Gebbert]

Hi,
i have slightly modified the html output of the test suite:
* valgrind memory check information added to the status column
* new known error messages added

I have added 4 additonal tests to the user defined location, to test
the error handling of the test suite (flag -u). I have generated two html outputs
with valgrind memory checks and error handling tests:

AMD machine:
http://www-pool.math.tu-berlin.de/~soeren/grass/GRASS_TestSuite/html/AMD64-2Ghz/Summary.html

P4 machine:
http://www-pool.math.tu-berlin.de/~soeren/grass/GRASS_TestSuite/html/P4-2.8Ghz/Summary.html

The test suite with the modification is available here:
http://www-pool.math.tu-berlin.de/~soeren/grass/GRASS_TestSuite/GRASS_Testsuite-0.1.6.0.tar.gz

Have fun,
best regards
Soeren

btw:
there are lots of memory errors detected in some modules!
