Polish & minor bugfixes

* Improve matching of political parties.
* Fixed spelling of [Last Alliance of Elves _and_ Men](http://lotr.wikia.com/wiki/War_of_the_Last_Alliance).
* Applied XKCD #1288 before Technology so Google Glass gets replaced before Google.
* When a regexp is marked as not case sensitive, the original case is preserved in the span title. This simplifies the rules somewhat.
* I am not convinced Flogiston is a real thing. Google turns up nothing.
