A suggestion for beacon reroll output messages

Since I've rerolled beacons several times (including typing out the command, yes, this is a bit tedious), I've noticed the Invalid command... Type /help for a list of commands message, a couple of times. I'd like to fix the usually ignorable issue.

Here's some message output suggestions for the command /rerollbeacon:
If you are not in a lootrun: Do nothing, and send "You are not in a lootrun." to in-game chat.
If you are in a lootrun:
- If you can reroll: Send "Rerolling beacons..." to in-game chat.
- If you can't reroll while rerolls are available: Send "You can't reroll beacons right now." to in-game chat.
- If you are out of rerolls: Send "You are out of beacon rerolls." to in-game chat.
