Title: Clear button in dcc download manager

Created a clear button in dcc download manager. Clears requests that ended successfully, failed or were aborted.

Clear button is enabled when no row is selected and there are rows eligible to be deleted. Similar to banlist's clear button. Addresses second item of issue #672.
