Allow hover responses as a trigger action (Feature request)

This idea was inspired by a bug-finding mission which turned out to be an incorrect netmask, which was discovered only because I copied a very unintuitive ip/netmask combination out to ipcalc and asked it to explain.

I then thought it would be very useful if iTerm2 could display information about an ip/netmask on hover, this would have made it much quicker to spot the issue.

It seems like this could be implemented as a new trigger action that gets called when a matching piece of text is hovered, and the result of the command would be displayed in the hover box (could look much like an annotation). The result could be cached to prevent too much execution if needed.

Can you give me an example of an ip/netmask and what you'd want to see?

I've attached a screenshot, hopefully that works, that's a rough guess - screenshot didn't capture my mouse pointer so you might need to imagine it's hovering over the selected IP address. I imagine the content of the popup box is itself the result of a command - this example is part of the output from the command ipcalc 10.0.62.0/24

I can imagine this being useful for a variety of things though, not just IP/Mask - you could use it to give you popup definitions of those ghastly network domain hostnames (usually ncdis05x, each letter with its own meaning), WHOIS results for domain names, IP/NS lookup for IP Addresses etc.

It might be more useful if you can hit a key combo to open the popup in a new terminal or copy it to clipboard or something, but even just the hover itself would be very useful.
