Release 2.0

This is a new major version; backwards compatibility is not possible; these parts will not integrate with v1.0 parts. Many of the changes in this release are on the back-end; with the code now in a state where it will be easier to adapt and maintain going forward. However, some of the benefits of those changes are present in this release; primarily the new flexibility has allowed for many more alternate parts to meet the diverse needs of the community.
Changes to the actual parts:

1. A surface-mounted hanging bracket is provided; and alternative filament brackets that allow for straight line paths to the MMU when hung from a desk surface. A template for drilling is also included.
2. Solid walls are available. These will reduce visibility for troubleshooting, but require less filament to print and (depending on infill settings) will likely weigh less.
3. Drybox parts have been added for external walls and the bottom frame. These maintain more of the hexagonal styling (unlike the solid walls) and the bottom frame is also sealed. Some leakage is still possible in through the top frame, but it should significantly improve performance in wetter environments. Adding desiccant packets to the bottom frame may also be advised
4. Better fitting for frame parts, especially the top frame -- we've been testing with no glue and so far have seen acceptable results (although for now, we'll still recommend glue)
5. Significant improvements to the documentation
6. A print-in-place filament wheel is now provided -- performance is not ideal but it is a functional alternative for anyone unable to source MR126-2RS bearings.
7. Additional direction (straight and "reverse") for filament paths; allowing for surface-mounted installations behind the MMU3 or straight in/out paths if those are desirable.
8. 8 and 12 filament channel frames/guidewalls have been added for ERCF or other high-filament count solutions
