* Added redirect to section feature. Use it wisely.
* Added a configuration variable allowing the "break out of framesets" feature to be switched on and off. Off by default -- there's all sorts of flashy frameset gadgets around, outright abuse is more rare, especially for small default installs.
* Refactored URL fragment handling.
* Made Title::secureAndSplit() slightly more legible.
* Refactored makeGlobalVariablesScript() -- it's not particularly convenient or maintainable to pass all global variables through the template array. The array is there for BC, not flexibility.
