I think the original Project Page extension does it by installing an IDE Notifier (see TProjectPageNotifier below). I don't think it has anything to do with the Project Manager. It simply listens to notifications about files which are being opened in the IDE and if it's the project page it will open it in the embedded browser instead of the default HTML designer. Here's my attempt to reproduce this functionality for Delphi 2007.
1) package:
package projpageide;
{$R *.res}
// ... some compiler options snipped for brevity
{$DESCRIPTION '_Project Page Options'}
{$LIBSUFFIX '100'}
{$DESIGNONLY}
{$IMPLICITBUILD ON}
requires
rtl,
designide;
contains
Projectpagecmds in 'Projectpagecmds.pas',
ProjectPageOptionsDlg in 'ProjectPageOptionsDlg.pas';
end.
2) data module with an action and a menu item to add to 'Project' menu:
unit ProjectPageCmds;

However, I don't know what effect the "Resource Folder" has. The option can be stored in and read from the .dproj file, it's also checked that it exists but I don't know how the original extension uses the folder path. If you find out please let me know, I'll include it in the code.
Also, part of this code is copied from my answer to another question of yours, which I compiled (and briefly tested) in Delphi 2007 and Delphi XE. This code was only compiled and briefly tested in Delphi 2007.
Hope this helps as a starting point, at least.
