Removed led pin definitions

Additional pin definitions hide cases where an onboard pin and externally
used pin conflict.

Having the motors defined with the same pins as the built in leds adds to
this issue.

The LED pin definitions have been removed to avoid confusion.
Update SonarDemo.c
Changed tMotor* array to contain 2 pointers instead of 12
Removed .orig files from RASDemo. Refer to previous commits
Merge branch 'master' of https://github.com/ut-ras/Rasware2013
Formatting in EncoderDemo.c
removed dependnce on UARTstdio

We used 3 functions from UARTstdio were : UARTgets, UARTputs, and Stdio init.
all three functions are simple, so I rewrote them.
I would like to point out that this is primarily to make linking of RASLib easier and to avoid '#include'ing a C source file.
Got uart.c compiling again
Cleaned up rasware.

Removed some unused files, added a few include paths
Created module for Pololu gpio based line sensors

- For Pololu QTR-8RC
- Integrated with RASLib
- Fully tested and working
- Timing values somewhat arbitrary, gives about 1.5 inches of range
Made linesensor.h polymorphic
Changed RASDemo to reflect new RASLib
completed function pointer idea
hidden to _, and created binary
Merge pull request #30 from ut-ras/fls_oop_suggestion

Fls oop suggestion
renamed LineSensorDemo, fixed inaccurate comment in linesensor.h
Merge branch 'master' of https://github.com/ut-ras/Rasware2013
Line following tested on official contest board.
