bulk operations through the UI

[lior-antonov]

I think there should be a mode that lets you select documents in the tree for bulk operations(delete, export, etc.). It can be nicely integrate with the branching algorithm for the tree to select entire branches.

For example in a case where I need to delete all DB instances of my LSM simulation its a lot easier if I could select them from the UI and delete.

delete bulk is done, which other actions do you want?

Thats it for now. We can implement the export utility with this later.
