So far all subclasses implemented filtering on their own which doesn't
make much sense. Now one can set filter keywords and a filter type for
all ResourceModels. Subclasses simply have to call
ResourceModel::itemMatchesFilter( ResourceItem ) in order to determine
whether an item should be hidden or not. Additionally they have to
implement the updateFilters() method in order to update their internal
management data each time the filters change.
When you press down or up while browsing in the resource browser,
it plays the sample.
FIXED: When you click on the keyboard in the resource browser, and then
click on the treeview, it didn't transfer focus.
Make sure preview is stopped as soon as a drag operation starts. This
is done by overloading QAbstractItemView::startDrag() and emit a signal
from there which is connected to an according slot in ResourceBrowser.

Actually enable dragging items. No further code is required here because
everything else is handled by the model and QTreeView base class.

Naming classes like ResourcesItem or ResourcesDatabase is bad style,
therefore rename all classes and files to be Resource*.
