Issue STUDIO-4743: Drag item from metadat explorer and create expression
As a user, I want to be able to drag an item from the DataSense explorer into a text box and have an expression generated for me. Acceptance criteria: * Must work with payload, variables, and properties * Must use "." syntax * Must properly escape properties, i.e. foo.'bar baz' * Must support Maps and POJOs * Must handle things correctly if you drag in an existing expression vs an empty text box * Must support XML - TODO: what's the valid way to do this?
