Added new package Camellia. (#8190)

* Added new package Camellia.

* Fixed an issue with a missing blank line.

Added a couple more Trilinos packages (things I expect to depend on eventually).

* Fixed a couple issues raised by @adamjstewart.

* Specified 4.9.2 as the supported MOAB version.

5.0.0 causes build issues on Macs during the link of Camellia's drivers.  The issue is that we end up with -framework -lAccelerate in the link line, where it should read -framework Accelerate, I believe.  I'm not sure where this comes from, but 4.9.2 does not have this issue.

* Trimmed slightly the Trilinos requirements.

Also deleted a blank line that had spaces in it because the Travis-CI thing didn't like that.

* Reduced length of MOAB description (Travis-CI complained).

* Reduced the MOAB line further; didn't quite get there last time!

This is to satisfy Travis-CI's requirement that the description be less than 80 characters long (E501).

* Put in my GitHub handle, in place of an allusion to my email address.

Also added a new argument for Camellia build, and made the MOAB description longer (thanks to @adamjstewart's note that long lines are allowed so long as they are not split).

* Added MPI dependency.

Added explicit OFF for MOAB enablement when ~moab.

Swapped order of variant and version.
