overhaul of build system (#54)

[edlins]

Fixes #50.

• overhaul of build system every folder has CMakeLists.txt for modularity examples/ excluded from default make one config.h for all targets fix olaclient.c #include <ola/OlaClientWrapper.h>

• update build sequence exclude PCA9685test from default make

Minor code changes but major build changes. I think this is enough to justify shipping 0.7. I've also developed build scripts that are compatible with raspbian-ua-netinst for headless automated provisioning. Simply dd a raspbian-ua-netinst image onto a micro SD card, add a customized post-install.txt, pop the SD in a pi, power up, wait 30 minutes, play! This will give you the smallest, absolute latest, fully upgraded, stable release of Raspbian with sources compiled, installed, and ready to run. Such provisioned hosts will be my dev envs for all future work.

TODO:

• readme
• changelog
• readme for libPCA9685/netinst/
• readme for picontrol-netinst/
• merge master netinst/ changes back into develop DONE

Hmm, thinking this might be a touch premature. Will investigate raspberrypi-ua-netinst and custom installers.
