Slc-linkcollection

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

- Added new styles to linkbox, provided by cornae. Reference: Syslab 1152
[cornae, thomasw]
- Added anchor and corresponding "Go up" link. Reference: Syslab 1152
[thomasw]

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

- deactivated setting the div's height to maxheight 253 [thomasw]

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

- set a class denoting the currently selected item also on the <li>, not only
on the <a> tag [thomasw]

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

- Nothing changed yet.

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

- Bug fix: the parent folder could be selected as a link even though it isn't a
document
- Feature: scroll to the top of the linkbox when a document is displayed
without causing the page to jump up and down for longer and shorter
documents.

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

- linkcollection can now also be used on ATFolders. For the Annotations-factory, I had to use a somewhat
awkward naming & inheritance construct, so as not to break existing linkcollection instances.
- added a BrowserView (linkcollection-view) for displaying contents of a Linkcollection
- enhanced search mechanism to distinguish between folder and document (thomasw)
