Universal Controller v1.2.1 RC1

Whew! Spent about 2-3 hours tidying up the board and getting everything all nice and pretty and also easier to assemble. Here's a quick changelog:

* Added real silkscreen outlines of polarized connectors
* Thanks to above, connector text will be visible after connectors are added
* board is slightly bigger, now 2.75" * 4.20"
* moved bottom components to allow mounting of heatsink on L298N easier
* spaced apart TIP110 to hopefully make it possible to get all 3 in.
* updated release package script to make filenames easily understandable (hopefully this will fix our manufacturing problem as well... to an non-native english speaker, SilkSCmp vs SilkSCop doesnt make much sense. heck it doesnt make much sense to me, and i've lived here 23 years!)

I've attached the file. Please peruse it and suggest any *cosmetic* changes or point out any huge flaws. You have til tomorrow to let me know. At 7 or 8pm EST i'll be submitting the order for new boards (53 to be exact...)

hmm... did anyone look at this board? anyway, i ordered 65 of them as well as released it on sourceforge. cant wait to get them back in stock!
