Ported to libdockapp 0.5.0.

This release features fixes and a new mode to calculate time
remaining based on the changes in remaining capacity.

This release implements the libdockapp port, and a capacity
mode for calculating time remaining (as opposed to the
normal current rate mode). This mode samples the
remaining capacity of the battery and notes the time at
which it was sampled, and uses a history of samples to
estimate the rate of drain on the battery. From there it
calculates a value for time remaining. Also, various code
cleanups have gone in.

Some bugfixes were made.
