MVE: add methods is_mesh_edge and get_faces_for_edge to VertexInfoList
DMRECON: allow controlling verbose output

Detailed information on queue size and the number of filled pixels
on stdout is not relevant when e.g. running dmrecon from UMVE, so
make that controllable.
UMVE: disable verbose output from dmrecon

Progress is shown in the GUI, so don't print it to stdout.
DMRECON: implement fancy progress bar

A progress bar rendered with ANSI escape codes is more informative
and more visually pleasing than the log output. Allow the user of
dmrecon to select silent, simple or fancy progress output.
