Offer pysqlite3-binary as a solution instead of compiling your own

[pmdevita]

The Readme points to some instructions for building pysqlite3, but that may not actually be necessary. The pysqlite3 project offers precompiled binaries, I was able to get things working through just pip install pysqlite3-binary.

pysqlite3 does not replace sqlite3 though and by default, it seems Django will still attempt to import the normal package. I had to add these lines to my settings.py to get it to work.

# these three lines swap the stdlib sqlite3 lib with the pysqlite3 package
__import__('pysqlite3')
import sys
sys.modules['sqlite3'] = sys.modules.pop('pysqlite3')
