Added new option to enable/disable 'Data Conversion warnings', ENABLE_CONVERSION_WARNINGS, when using CMake-based builds.

Added a custom cmake test configuration file to override the default '50' warnings when submitting to a remote dashboard.
Updated Building-with-CMake file.

+		If cmake is having problems finding the parallel HDF5 install, you can specify the location manually:
+	
+		-DENABLE_PARALLEL=ON
+		-DHDF5_LIB=/usr/lib64/openmpi/lib/libhdf5.so
+		-DHDF5_HL_LIB=/usr/lib64/openmpi/lib/libhdf5.hl.so
+		-DHDF5_INCLUDE_DIR=/usr/include/openmpi-x86_64
+		
+	You will, of course, need to use the location of the libraries specific to your development environment.
