#69 Move 'Restore Version' functionality to separate page

[Christoph Wille]

Current Situation

The 'Restore Version' functionality is part of
default.aspx.

Proposed Change

Move the 'Restore Version' functionality to a page
separate from default.aspx (eg RestoreVersion.aspx)

Advantages

People using FlexWiki with custom forms based
authentication can easily secure the editing
functionality (new, change, revert, delete) using URL
authorization in web.config without having to touch
FlexWiki source code.
