Bug 514394

With growing lists of regex rules, it becomes difficult to keep track of them and what they do, so it would be nice to have a way to label them and group similar rules with each other. This would be purely used for displaying the rules and wouldn't have any impact on how they function.

In my use case, I keep a large list of rules for matching against screenshots and recordings and renames them into a consistent format. This involves keeping potentially multiple rules matching against different formats from different programs, so it would be really nice to be able to group rules based on which program's formats they match against and be able to label the individual rules on what specifically they're matching.

Currently, I work around this by using empty rules to space groups out and have dummy rules serving as group names, but this obviously isn't very ideal.
