Added Data Processor using Nodes (#152)
* Added imnodes

* Added basic data processor view. Still needs to be cleaned up

* Make sure all attached links get properly removed when a Node is deleted

* Cleanup and API exposing

* Added data provider overlays and integrate them with the data processor

* Optimized data processing

* Node UI enhancements

* Added support for all themes to the nodes editor

* Improved data processor context menus

* Fixed data processor context menu showing up everywhere

* Make hex editor context menu behave the same as data processor one

* Add different node pin types and prevent incompatible ones from being connected

* Don't require explicitly marking node as end node

* Fixed plugin copying

* Added some more nodes
