Change record field defaults

[JJL772]

• Allow the IOC engineer to change various defaulted fields in the dbLoadRecords declaration
• Default ADEL/MDEL to 0. Computing a default for this was apparently a huge landmine-- oops!
• Bump CI submodule

Closes #62

LGTM. I like the inclusion of other configuration fields here as well. This will help make our terminal configurations more maintainable and transparent.

Once you make a release of this module update, I can update the IOC to enable the use of these new configuration flags.

Sounds good. I'll tag this as R1.7.2 and do the release today.
