[stormyfacts] fix behaviour of alert factoids with prefixes

[m4v]

in Encyclopedia calling for "!foo lots of text" triggers ubottu's iamnotsmart reply. Stormyfacts does the same *except* for factoids with the +alert tag (such as !ops)
originally I thought this would help users that forget to use the pipe char, but after a while of looking at #ubuntu I see now the people that forget it the most are actually trying to disrupt the channel, this change would make them even more disruptive.

Gotta remember to change it back to how it was.

[m4v (m4v)]

Noticed that #debian uses the !ops call without the pipe, so It could be useful to make it work in #ubuntu as well, people idling in both channels won't have to think which channel is needs the pipe and which don't.
Also factoid calls have a length check now, maybe the abuse won't so bad now and this bug can be set as wontfix.

Ask ops what they would like better.

[m4v (m4v)]

as a clarification to those that have not seen/read our email to -irc yet. All factoids needs the pipe for prefix text:
 * !foo | asd asd asd (will work)
 * !foo asd asd asd (will not work)
the only exception is when the prefixed text is a nick:
 * !foo nick (in this case not using the pipe will work)

This bug is for the special case of allowing "!ops asd asd asd" to work.

[m4v (m4v)]

I made it so "!ops asd asd asd" sends an alert but nothing else, this is a middle ground between making the command work normally or send a failure reply like in Encyclopedia.
