newui: index; select a current set, add members to it

This change adds 2 buttons to the toolbar.

1) setAsCollecButton_ is enabled only when a single item
(which has no content) is selected. When clicked, the button
sets that item as the currently selected collection/set
(BlobItemContainer.currentCollec_).

2) checkedItemsAddToSetButton_ is enabled when
currentCollec_ is set and some items are selected. When
clicked, it adds the selected item(s) to the current collection.
