* NyaaSpam.cs: Remove redundant IrcShow calls by placing the call
  outside the if-else chain.

* UrlTitling.cs: Split up triggers, so that the trigger that can work
  with a query message is called when MeidoBot receives a query
  message (disable/enable need to know the channel).
* NyaaPatterns.cs: Consolidate identical code in Get and Remove.

* NyaaSpam.cs: Move pattern extraction to its own function. Also make
  GetNumbers and GetRange static.
Move Config into its own file.
* NyaaFeedReader.cs: Small changes.

* NyaaPatterns.cs: Guard against iExclude being negative.
