New section - Unfinished Designs

NOTE:  Many of these designs are unfinished (have no specs), but I will be completing some of these in the future, and then moving them to the regular prototype section.  Many were designed with a purpose in mind (those I will finish), while others were just random doodling.  Many of these feature small (or major) design features that I later incorporated into completed/better designs.

Also note that I have FINALLY uploaded some of my capital ship designs.  At least two of them will be "completed", sometime.
