python-slugify depends on a GPL library

[sekrause]

While python-slugify itself is BSD licensed its dependency Unidecode is a pure GPL library. It's technically not a problem for python-slugify because the licenses are compatible, but it should probably be mentioned somewhere because this makes python-slugify unfit for most commercial deployments.

Just nitpicking: A lot of commercial software is nowadays website like. Software-as-a-service model with GPL is totally fine, because you are not distributing the software (binaries). In fact most of the websites are built on GPL'ed system (Wordress, Plone, Drupal, etc.) - so "unfit for commercial deployments" should be "redistributing the software containing python-slugify" here.

python-slugify is NOT a "derived" work from Unidecode. It simply requires a translation API that is
currently satisfied by importing Unidecode.

"The GPL is a copyleft license, which means that derived works can only be distributed under the same license terms". ( Wikipedia )

Hope this helps.

@sekrause Please note that version 2.0.0 always prefers Unidecode however, it gracefully falls back on text-unidecode if it is already installed. (Just an FYI)
