Cleanup: Remove unused node editor button event defines

These defines seem to be left over from the initial implementation
of the node editor. In a few places the values were used in button
creation, but the callbacks never checked the value anyway.
Node uiBlocks also had a callback what would never do anything
since the value it checked for was never used.
