AnimAll: Enable keying of shapekeys on bezier curves (Thanks to Aligorith for yet another API fix!). Also one extra effort to make the use of shapekey animation clearer.
Fix for error in keyframing lattice points. Thanks Aligorith for the pointer
AnimAll: Adding info message for preventing people to add keyframes for Shape and Points at the same time. Will not disable it because maybe there's a valid use.
Add 3D Printing category for addon.

This adds the 3D Printing category to the addon such that it's placed in a "3D Printing" tab of the 3D View Toolbar.
Update addon for 3D View Toolbar tabs.

This adds the "Navigation" category for the addon, thus assigning it a tab. Due to this, I've also made the panel open by default. It was closed.
