Added SMD Button and USB Mini-B Connector

+ COM-08720 (Mini Push Button Switch - SMD) to category "Components"
+ PRT-08612 (JST Right Angle Connector - White)
+ PRT-00587 (USB Mini-B SMD Connector) to category "Prototyping"
+ 603 LED to new folder, "Created Models" in folder "Bare Components"

There is a ton of detail in the button, but the USB Connector is very
basic.

EDIT:  Just put in a JST connector and a 603 LED.
