Setup: add buttons to remove patching (either from elements, or from controllers).
Added a bunch more generic icons for things that could be useful in the application.
Added a 'reverse mapping' from an output data flow component to the source output controller and output index. Not an ideal way of doing it, but the whole area really needs some rework.
Setup: added the ability to 'select' particular items in the element view or the controller view.
Setup: added buttons and functionality to trace a path from an element -> outputs (or vice versa) and select the corresponding items.
Added some more icons.
Clean up the setup buttons on the main form, and make the new single-page setup form the default.
Setup: add buttons for element operations as well, to keep a consistent look.
