Bring up drag option in context menu

Bring up drag option in context menu

This reverts commit ddc255acd3b2955c28c29af67104881f1840b52d.

Implementation of Drag&Drop was splitted into two parts. First one
implemented EFL`s port for D&D with default behavior, which is
dragging on long press. Second part changed default behavior to
starting D&D after choosing proper option from context menu. After
merge of first patch issues was raised that one cannot open context
menu for URL links. Now both parts are merged so this issue does not
occur any more.
