Correct parsing logic for ABLMeanBoussinesq

[mbkuhn]

Summary

Previously, the read_temperature_profile input could be specified to "false" but would still be used. This is replaced with the following logic:

If read_temperature_profile is not in the input file, but tprofile_name is, then the temperature profile will be used. Alternatively, the temperature profile will not be used unless read_temperature_profile is present and true.

Any oppositions to this new approach?
