Custom Brief Option in Schema Definition

[roikle]

Issue: When creating a schema definition, sometimes you will need to modify the brief for some form of custom functionality / appearance (e.g. including "{{#if ... /if}}" content, custom styling, or wanting the brief content order to appear differently than the stated order in the definition). This results in needing to remove the definition file to prevent the unintended overwriting of the custom brief.

Solution: Provide a custom brief option in the definition file, which if supplied by the builder, will force the brief to be generated from that provided content, instead of being auto-generated.
