Decided to not support precompiled libraries.

The reason for this is that there are simply too many platforms to
maintain compiled binaries for. Better to just include the c file as an
external link in your project, and compile it yourself.
Moved all uart functions to one file: uart.c
Added mcclurg_datatypes project

Initial support is for ring buffers, uint8_t booleans, and #defines for
ascii codes < 32.
Updated adc_server demo

I also remembered to add the solution file.
