Updates and more structure

First things first: Thanks for open sourcing DIWire Bender. That being said (and I hope you guys do not take offence to this) but in general I feel that the documentation could really use some organization. Most of the information is scattered through a variety of locations, Pensa's Blog, Google Code repo, and multiple BOM files. In addition the repo on github doesnt seem to be in sync with the official repo on google code. To remedy this I set out restructuring your git repo in an attempt to bring all the information into a single location easily accessible, viewable, and forkable.

Here is what I did:

1.) Pulled latest code from the google code repository; merged changes into existing repository.
2.) Added all files from the latest BOM download archive
3.) Converted all STEP files to STL for easy 3d printing
4.) Added in additional parts from older BOM that were missing from the new BOM archive (was this an accident)
5.) Renamed all 3d-printed parts to fit standard naming convention
6.) Added in gplv3 and cc-by-sa licenses
7.) Migrated readme document to markdown for display on github and added in several new sections
8.) Change BOM format to use a similar format to that of kitBOM
9.) Migrated BOM from excel document to markdown (again for display on github)

TLDR; So i did some serious reorganization to your repo, added in an assload of readme info, updated BOM and added stls of all printable parts.
