Prevent long results from flooding

[dgw]

Certain queries generate results with many lines. The module currently outputs the entire result, no matter how many lines it is, causing flood and potentially getting the bot kicked or delaying other modules' output in other channels.

Before supporting wolframalpha 3.0 (#5), this should be fixed in the current version.

Rizon's Internets bot deals with the problem by sending the result in NOTICEs to the trigger.nick if the result is too big. Alternative solutions:

• output the first 2-3 lines, and then put a link in chat to the Wolfram|Alpha site for the full result
• output the first 2-3 lines, then send the rest via notice to the calling user
• output the first few lines, then buffer the rest in some kind of continue mechanism (arguably the least user-friendly way to handle this for IRC)
• refuse to output a result if it's too long; just reply with a link (actually the least user-friendly choice)
