1.1v UART Wrapper Module Added

New UART Wrapper module added. Some minor fixes in GPS functions and
new #define added to constant int values. GPSgetMessage() is in process
of implementation using UART wrapper.
1.1v Arduino Code Completely ported to ANSI C

All methods and functions are already ported. In this new version, the
function GPSgetMessage() use the UART wrapper to obtain a char* with
the GPS message.
1.1v All upToDate

Any changes to the code..
