EndCanvas unselect one node

[Sagigamil]

HI!
I noticed a bug in ImNodes::EndCanvas() function.
It's reset the single_selected_node to null if ctrl and shift keys not clicked,
So when I click a node with mouse only, the function ImNodes::Ez::BeginNodeset select to true,
but in next call to this function, select becomes false.

I don't sure why you made ImNodes::EndCanvas() function act and if it's really a bug,
but I think that after clicking a node it should be selected without using shift or ctrl keys.

I am unable to replicate this issue in a sample application. Can you? Also could you link exact lines you think are at fault?
