bump version

we have quite a few commits to come so let's identify the new version
in the meantime.
allow more translation

map link text (and console 'y' prompt since it also accepts 'j')
better inclusion/exclusion

basic function for exclusion. will make this encompass all requirements
later.
don't re-raise exception

the IOError raised naturally here would be more appropriate, just as
helpful, and won't change the program flow.
don't use a string to represent a comment
changes to thumbnail handling

- use blank image if no thumbnail exists
- use standard string interpolation throughout
use unicode throughout for html output

I'm sure I'll have missed a few cases but this should permit input
files to use extended characters.
process images in parallel

quite a bit faster this way.
missed a unicode string

deleted promotion string by accident -- it's back now
