Layer picking tools
Submitted by Mike Bjorkegren
Created attachment 358536 zip with 3 patches based on 0ef3795f
This includes two features related to picking layers.
A dedicated layer picking tool that basically copies the picking functionality of the Move tool.
A per-layer toggle that allows the user to disable picking for that layer. This makes it easier to pick objects under large semi-transparent layers.
I've split it into three patches, one dedicated to setting the hotkey for the pick tool to 'Q', which was already used by the Align tool. I'm not sure what the policy is on switching hotkeys, so I left that as a separate commit. The reason for choosing 'Q' is that both the Unity game engine editor and Autodesk Maya use Q for the select tool. I found that Shift-A was available, and that seems like it might actually be better than Q for the align tool.
