Status messages had different length ("no changes in file" vs "updating
file") and were generally too long, making it hard to see at a glance
what changed after running Bakefile.

Instead, use Subversion-style status indicators in the first column,
with filename following after a tab. Status letters are 'A' for added
output files, 'U' for updated ones and '.' for untouched.

This should be understandable too and is easier on the eyes.
