Title: URL shortening speed improvement

I've made some improvements in the way ShortUrl objects are created:
-add database index for original_url field;
-use get_or_create QuerySet method;
-if exception occurs, other than URL validation (violation of unique constraint) repeat
the process of generating shortened_url and checking for token exhaustion until object
is created.

I also perform tests usint python timeit module with PostgreSQL database createing
10000 records.
