Make img2twit message length configurable at runtime, improve the initial
guess by smoothing hard colour gradients, and fixed the bitstack copy
constructor to avoid corruption on exit.

Add proper Unicode handling to img2twit. This includes an UTF-8 encoder/decoder
and a special bit stack that can handle arbitrary bases within its stream. The
image encoder and decoder are now separate code paths.

Tremendously improve img2twit.cpp: only compute the new error around the
updated pixel, compute bit allocation at runtime, weight operations in
order to try usual "winners" more often, increase RGB allocation size.
