slug cli: slugify for filenames

Some people don't have standards when it comes to naming files.

YOU ARE BETTER THAN THAT

slug renames files, turning nonsense into sense, like this:

slug 'Some_Client : BIG SCREEN layout.JPG'

# will rename the file to
some-client-big-screen-layout.jpg

Grinding all your unruly filenames into dasherized, lowercase, lower-ascii perfection.

Got a dir full of bad filenames?

slug *

will rename the lot. It'll only go one level deep, and it'll indiscriminately rename files and directories. Use with find for more elaborate requirements

find . -name "*.JPG" -exec slug {} \;

Go forth and slug.
