Initial commit

This includes support for printing battery, cpu, filesystem, memory,
time, and date sections. Sections with percentage values also support
the `display = bar` configuration to make them display a bar rather than
the actual percent. Finally, for relevant data types, colors change from
green to red as percentage approaches appropriate levels (eg: when
memory is high, color is red; when battery is low, color is red,
otherwise green).
