* Renamed PageHistory to HistoryPage. Brion gave me permission to do this a couple of years ago, I thought it was about time. Provides naming consistency with ImagePage, RawPage, etc.

Browse source 
* Moved historyLine(), beginHistoryList(), endHistoryList() and related helper functions to the pager class.
* Renamed HistoryPage member variables, removed "m" prefix.
* Added declaration for IndexPager::$mIsFirst
