TYPO3 Core

There are a few leftover classes inside typo3/ which
haven't been moved or migrated yet into the according
places.

1. typo3/move_el.php. The extension classes
to PagePositionMap are now moved to
EXT:backend/Classes/Tree/View with according
names.

2. typo3/class.browse_links.php - several extensions
to the PageTreeView and the FolderTreeView.

The base classes (localPageTree and localFolderTree)
have been moved to
EXT:backend/Classes/Tree/View/ElementBrowser*.

The subclasses for recordlist (regular record picker)
are moved into EXT:recordlist.

The subclasses used in RTEhtmlarea are adopted to
use the new naming scheme.

All calls within the core have been adopted. As
backwards compatibility, the old class names are
added to EXT:compatibility6.

The ext_autoload.php inside EXT:core is therefore
not needed anymore.
