Plone-app-layout

------------------

- Update license to GPL version 2 only.
[hannosch]

----------------

- Removed notice about registered trademark from the footer, that's what (R)
means anyway.
[limi]

- Make sure the presentation mode warning (if the document has no headings)
displays properly. Fixes http://dev.plone.org/plone/ticket/10689.
[davisagli]

- Adding "deactivated" class to menus by default, so they won't flicker on load.
This fixes http://dev.plone.org/plone/ticket/10470.
[limi]

- Determine whether to show the history link in the byline viewlet based on
whether the user has the 'CMFEditions: Access previous versions'
permission, rather than based on whether the user is anonymous or not.
Fixes http://dev.plone.org/plone/ticket/10640.
[davisagli]

- Add an 'icons-on' class to the body when icons are enabled, so that icons
applied via CSS can also be controlled.
[davisagli]

------------------

- Only show the history link in the byline on the default view. This avoids
having the links in folder listing views.
[hannosch]

- The condition on the author link in the byline was reversed.
[rossp]

- Document byline should not show history link to anonymous users.
[elro]

------------------

- Fixed personal_bar.pt to not repeat the UL tag for each user action.
This fixes http://dev.plone.org/plone/ticket/10481
[xMartin, dunlapm]

- Fixed CMFContentIcon to not return a url if the getIcon lookup fails
in the same way that brain-based icons do. This fixes
http://dev.plone.org/plone/ticket/10466
[dunlapm]

- Cleaned up content history viewlets and overlays by eliminating
superfluous div tags from the output.
[dunlapm]

- Added apple-touch-icon (iPhone/iPad home screen icon) definition to
favicon.pt
[limi]

------------------

- The catalog brains icon return no icon if the type's icon_expr is
empty.
[rossp]

- Extend the have_portlets check to make it possible to force a portlet column
to be enabled even if there are no portlets.
[davisagli]

- Simplified Related Items to use a definition list instead of a fieldset -
it's really not a form.
[limi]

- Change keyword/tag viewlet to be independent of the surrounding language,
and to have a class on the separator, so it can be removed when the styling
requires it.
[limi]

- Update viewlets so that this package now defines the viewlet configuration
required by the Sunburst theme, and plonetheme.classic overrides that to
achieve the old viewlet positions.
[davisagli]

------------------

- Make icon descriptions' lookup of portal_type title less brittle for missing
portal_types (fall back to the portal_type id).
[davisagli]

- Further optimize the related_items view by avoiding an algorithm with
quadratic complexity.
