[FEATURE REQUEST] Emit event that indicates that no command event was emitted

[hashworks]

Example:
I have a command nfo <dirname> which get's information about a scene dirname.
However, the same can be triggered by a dirname in irc.received.privmsg parsed by RegEx:

<hashworks> !nfo Rayman.Legends.MULTi13-PROPHET
<Phergie> Here is some information about Rayman.Legends.MULTi13-PROPHET.
<hashworks> Check out Rayman.Legends.MULTi13-PROPHET!
<Phergie> Here is some information about Rayman.Legends.MULTi13-PROPHET.

The problem is that the plugin needs to determine duplication by itself, otherwise it will react on both command.nfo and irc.received.privmsg:

<hashworks> !nfo Rayman.Legends.MULTi13-PROPHET
<Phergie> Here is some information about Rayman.Legends.MULTi13-PROPHET.
<Phergie> Here is some information about Rayman.Legends.MULTi13-PROPHET.

I solved this by avoiding PRIVMSGs with nfo in the message, however this isn't the best solution.

Instead of listening on irc.received.privmsg one should be able to listen to a event that indicates that no command event was emitted, f.e.:

• no.command
• no.command.privmsg
• no.command.notice
