Comment and a method name change.
Working towards finishing the WebToIrc interface.
Some changes with regards to UrlTitleComparer.
Rework 4chan and archive.moe support. Add the ability to get Subject
and Comment of any post, not just the OP of the thread.
* ChanTools.cs: Small changes.

* Ebml.cs: Make sure every long or long[] variable that is an ID has
  the postfix Id.

* Jpeg.cs: Add yet another segment that a JPEG file can begin with.
Use WAL journaling by default, make the lambda correctly captures the
intended variable - it doesn't 'recapture' when the field is changed,
so it was a useless field. Remove paranoid check for null.
Some cosmetic changes and small performance improvement.
Code that should be deleted...
Slightly adjust BrainFrontend, moving the Seed and Sentence selector
funtionality (or at least part of it) out of the main class. This
improves the readability.
Have the database return the sentence as an array of words/strings,
since BrainFrontend needs to check each word's wordcount anyway... so
we remove an unnecessary string.Split.
