Xm-theme

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

- Added cachesettings.xml to store our xm rules.

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

- Added extra viewlet for the my project stub in portaltop. [jladage]

- Fixed issue 100, insert list of projects on DOM load. [reinout +
mark]

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

- Style and portlet cleanup by laurens and jladage. [laurens, jladage]

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

- Overrode the login portlet template, added a footer to the Login portlet. [simon]

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

- Also show Documents as attachments. [mark]

- Remove the viewlets which showed the iterations grouped by
state since there is a porlet to do this. [mark]

- The username is not rendered on each page but on DOM load. This allows for
caching based on roles instead of each user.[jladage]

- Images are moved to a skins folder, so they get cached properly using the
HTTPCache. [jladage]

- The username in the personal_bar now links to the author page instead of the
dashboard. [jladage]

- Added 'Iterations:' in front of the open/current/closed iterations list and
show it only if we have iterations in the project. [fredvd]

- Moved the employees_overview page to Products.eXtremeManagement.

- Made the employees overview page much much faster. The billable
percentages are not quite the same as from the bookings per month
pages they point to, but that is for another day. [maurits]

- Protecting the big employees overview page with the Manage Portal
permission now. [maurits]

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

- Added locales/en to work around i18n bug: with e.g. Dutch and
English as allowed languages, Dutch as site default, English as
browser language (the only one or not), you would get Dutch for all
translations in the xm.theme domain, even though the rest of the UI
is in English... [maurits]

- Fixed the livesearch.js customization to work with Plone 3.1.x We have to drop
support for Plone 3.0.x for this one, because jquery.js is not available.
