* Implement accessors for isHardblock() and getRangeStart()/getRangeEnd() in the same fashion.
* Make the corresponding variables private, removing external accessors. This required updating AbuseFilter with non-B/C code, so I also implemented the rest of the changes I've made to the blocking backend in that extension.
* Move the "get an IP range which encompasses the given IP/range" logic to Block.php; will be needed later... :D
* Write array literals with one item per line. This makes diffs which add or remove items far easier to interpret, and makes merging such changes feasible. And it looks nicer too.
* Use line breaks to show the logical structure of your code. This enhances readability. Bring similar elements in a list into alignment, in order to reveal the differences between those elements at a glance.
* Removed a fun game of spot-the-difference in AbuseFilterHistoryPager::getQueryInfo(). If I want fun games I'll play UFO:AI.
* Moved some oddly placed assignments (in expressions) to their own statements: such assignments reduce readbility.
