Bug 1094154

Description of problem:
This is a followup of the rejected Bug 1090875 which asked for applying move*Permission defaults from parent site. The present aim is to ensure for all page creation forms, that they use consistent defaults for all kinds of permissions.
The page creation forms for which this applies:
I. Page Creation Wizard accessible via Toolbar > Site Editor > Add New Page 
II. New Page accessible via Toolbar > Group > Administration > Page Management > Add New Page
III. Create Page accessible via Toolbar > Manage Sites > Edit Navigation > Create Node > Page Selector > Create Page
For each of them, the defaults should be set as follows:
(1) For portal pages the access and edit permissions should be taken from the parent site.
(2) For group pages, the the default access permissions should be set to all group members and edit should be set only to the given group's members with the membership type defined in navigation.creator.membership.type configuration parameter of UserACL service.
(3) For any kind of page (portal, group, etc.), the move*Permissions form defaults are taken over form the page.xml template chosen in the given form. If the given form offers no page template choice, the empty template should be used.
In the present implementation, the named requirements are mostly met, however the code is spread over several classes, and is not always 100% consistent, which should hereby be fixed.

Version-Release number of selected component (if applicable):
JBoss Portal 6.2.0.ER1

How reproducible:
Always

Steps to Reproduce:
Open any of the named page creation forms and check the permission defaults preset by the portal. OK if they match the rules named above, unexpected otherwise.

If there is no UI for the permissions in the give page creation from, create a page and subsequently open it in Page Editor, open Page Properties, and check if the stored permissions.
