Generic HF calc type

[jmmshn]

Added a generic calc type for HF calculations.
Currently, the calc type checker just checks the setting against some stander Hybrid functional settings.
If none match, the run_type checker will move on and categorize the calculation as a run_type:"PBE".

This creates a "HFCus" category for custom HF calculations.
The most obvious usage case is when users set AEXX to match the band gap of a material.
