- slide toggle release notes to keep page over simplified and add style for html tag on to prevent content jumping around when scrollbar appears.
- simplify the first tab of the SystemInfo block and put all details in a new Diagnostics tab (later most of that will be moved to the diag dump file).
- Rename alternate method to CanDelete in the SiteService
- add delete capability to PageList block and extra CanDelete method in PageService.Partial that prevents pages which are being used as Site 'special pages' (login, default, register, page-not-found).
- only show delete button on LayoutList if authorized to 'edit' and fix bug that was preventing warning dialog from showing if the CanDelete returns false.
