Parameterize Maestro API test runner test suite settings

[jng]

Currently the Maestro API test runner's test suites are information that's compiled into the executable. For greater flexibility, such information should be able to be passed in from the command-line and such conditional tests should be able to programmatically ignore any tests that cannot be executed under the current environment conditions (eg. Ignore testing the LocalNative tests if we don't have the official MapGuide API assemblies with us)

[jng]

All test parameters can now be set and read from a TestMaestroAPI.xml configuration file.
