[patch] Apply filters to sql query in BP_Core_User::get_users() (has patch)

[boonebgorges]

Until we get better filtering all the way up the bp_has_members chain, this is a harmless substitute.

Paul suggested passing the array along too, which makes it all the awesomer. See second patch.

Would like Andy's blessing before we add filters directly to SQL queries. If you can get Andy to thumb-up this in here, I'll make it so for you. I'm thinking there should be another way to do this.

[boonebgorges]

One better way is to have more passable parameters to bp_has_members(), but that kind of rewrite seems like a stretch for a maintenance release like 1.2.6. FWIW, WP's query.php has filters like this all over the place on its SQL queries, in particular posts_request right before the query is run.

(In [3224]) Add filters to get_users query. Fixes #2593. Props boonebgorges.
