Remove limit / offset from queries

[riseoflex88]

I'd like to remove the offset / limit settings on a query (to work out the total count of results of a more complex query)

I've seen this pull request which seems to cover what I'm referring to:
#31

But I'm not sure it's still working as I'd guess the code has been reformatted a fair bit since then as its not working for my setup (using the BasicEngine).

		$count_sql->limit(NULL);
		$count_sql->offset(NULL);

PHP Fatal error: Uncaught TypeError: Argument 1 passed to Latitude\\QueryBuilder\\Query\\SelectQuery::limit() must be of the type integer, null given

Fixed in version 3.1.1.
