Incorrect interface for execute_sql

[saintger]

Hello,

I had some problem related to the function interface of execute_sql in silk/sql.py.

Your interface is:

def execute_sql(self, *args, **kwargs)

With some code to retrieve the result_type keyword:

kwargs.get('result_type', 'multi')

However the interface in Django is different (https://github.com/django/django/blob/master/django/db/models/sql/compiler.py):

def execute_sql(self, result_type=MULTI)

In the case where we call without specifying the keyword:
execute_sql('single')

Your code doesn't give the expected results.

You're right. I'll fix this is the next version which will be soon. Cheers.
