Planter2 & Tray2

This is an upgraded/improved version of http://www.thingiverse.com/thing:1370581. The changes are:
1. Rounded planter compartment corners provide a more organic shape
2. Planter & tray top edge is rounded instead of flat
3. Planter compartments are tapered to make changing/removing items easier
4. Tray has higher sides so reduce likelihood of spills.

The tray from this part will fit the original planter if you only want to print that piece.
