changed to auto generate memory error suppression file

the version of the Qt libraries detected along with its directory
location is used to create the memory error suppression file during
cmake configuration and put it into the project binary directory
(tested with default Qt 4.8.2 and installed Qt 4.8.4)

updated the memory test scripts to use the suppression file in the
binary directory instead of reaching into the test directory; added
temporary regtestn script and regtest.bat batch file for testing
selected (working) tests
