Patch 1 add get_or_create function to shortener.py

[millerthegorilla]

This adds a get_or_create function to shortener.py so that repeated requests to shortener can return the same link if it already exists.

Hey, I appreciate the contribution however the requirements for a get_or_create function would vary considerably from project to project and so it would be better if this was implemented in the project using the shortener.

Some examples of how requirements can vary:

• We might want to do case insensitive matching of urls
• We may want to add additional uses to an existing shortlink if it already exists, alternatively we may want to reset its lifespan
• We may want to 'reuse' short urls created by other users or we might want to keep shortlinks isolated so a user can only 'get' their own.

Ah thanks. In my situation its not important who creates the links, as long as they are created so I missed it. I will change it as you suggest, many thanks.

Hey, just a fyi in case you're using this in your project - This would also get links created by users other than the one passed to the function. You might want something like:

m = UrlMap.objects.get(user=user, full_url=link)
