Plone.app.layout

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

- Made PersonalBarViewlet tolerate users who don't have a Plone user object, as
when using OpenID or apachepas. This fixes
http://dev.plone.org/plone/ticket/7296.
[erikrose]

- Use 'index' attribute rather than 'render' for setting viewlet templates, so
that they can be overridden using the 'template' ZCML attribute.
[davisagli]

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

- Applied patch from http://dev.plone.org/plone/ticket/7942 to ensure that the
'currentParent' marker is not True for items that have a path that is a
substring of the true path.
[optilude]

- Displaying 'Anonymous User' also when the comment creator is an empty
string. This fixes http://dev.plone.org/plone/ticket/7712.
[rsantos]

- Allow the use of the icon attribute on action directly instead of using the
actionicons tool.
[hannosch]

- Fix invalid leading space in all 'Up to Site Setup' links.
[wichert]

- Fixed permission in workflow history viewlet. This closes
http://dev.plone.org/plone/ticket/5507.
[hannosch]

- Made handling of self.context in portal.py consistent.
[hannosch]

- Rename the portal_url instance variable to site_url in the ViewletBase
class. This prevents getToolByName(..., 'portal_url') from returning
the URL string instead of the portal_url tool, which can causes unexpected
and subtle breakage. portal_url is still available but produces a deprecation
warning. It will be removed in Plone 4.
[wichert]

- Added viewlet for RSS link.
[fschulze]

- Added dependency on plone.app.viewletmanager.
[fschulze]

- Make viewlet managers in head section order- and filterable.
[fschulze]

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

- Added i18n markup to nextprevious.pt.
This closes http://dev.plone.org/plone/ticket/7537.
[hannosch]

- Catch KeyError for presentation or tableContents when document
has an out-of-date schema. Can happen when migrating from Plone
2.5 to 3.0. Fall back to False for those attributes then.
[maurits]

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

- Do not create an empty <ul> in the personal actions bar if there are
no items in it. This fixes an XHTML syntax error.
[wichert]

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

- Added i18n domain to comment.pt.
[martior]

- Allow non ascii characters in webstats_js code.
Fixes http://dev.plone.org/plone/ticket/7359
[naro]

- Fixed workflow history viewlet to handle entries with
usernames that don't exist any more (deleted users) and
also anonymous users.
This fixes http://dev.plone.org/plone/ticket/7250.
[rsantos]

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

- Made getIcon urls relative to portal root.
