Change CXXFLAGS for RPi compatibility
Planning notes for implementing the clock
Add note on expectations of reporting function
Remove LedClock class for testing directly in main.cpp
Implement an ugly but hopefully functional LedClock
First version that properly communicates with LED

The output still goes to the wrong place and it looks like it's transposed, but this should be fixable.
First working version of clock

It's not the prettiest code at the moment so I will definitely clean it up, but
it works and is readable. Most of the functionality is still in main.cpp, but
that will now change.
Move reporter classes to external files

Now they're also documented. I also slightly changed the implementation by
using multiple inheritance for the LedMatrixManipulator, which has now been
renamed to BinaryClockReporter.
Prefinal runnable version

Now most of the initialization legwork has been moved into a separate class.
I'm still not entirely satisfied though.
Reformat clock display

This is a bit more logical and intuitive.
Add install option to Makefile
Add license snippets to sources
Merge branch 'pi-next'
