ui: add search box to DataStore content

Browse Source 
which searches the whole tree (name & owner)

we do this by traversing the tree and marking elements as matches,
then afterwards make a simple filter that matches on a boolean

worst case cost of this is O(2n) since we have to traverse the
tree (in the worst) case one time, and the filter function does it again
