render capsules with more facets, tune some fits for new printer, add one more parameter to capsule code to better fit the mount slots to the capsule array, actually fix the sign of the previous fit parameter (was making things smaller, not bigger), modify calls to do the right thing

add rfit parameter to the capsule module, this is needed so that carving the slots for the conical section of the mount works better; also adjusted the radius of the conical section of the mount so that it fits the capsule array - the code there is probably not correct and needs to be revised
