v0.4.4 Additions to template mode and fixes

Adding some minor changes I made to the game in preparation for making the template mode usable. If all goes well players will be able to copy and paste structures in some meaningful way!

PS:  For some odd reason, my antivirus (Avast) hates my game exe file, so watch out for that.

Added:

• Template mode now copies objects and parents them to your template cube in preparation for spawning
• Each object has a build mode equivalent so that template mode can copy them

Fixed:

• Template box no longer collides with environment (sad wrecking ball noises)
• Fixed an error when clicking in build mode without having chosen an object to spawn
• Player can no longer shoot in flymode (the bullets were flying out of the player model and not the camera)
