Deprecate any hooks & functions with improper names

[frankiejarrett]

We need to create a new include file for housing deprecated items e.g. includes/deprecated.php

All actions, filters and standalone functions should be using the wp_stream_ prefix.

• stream_query_args => wp_stream_query_args
• stream_test_ => wp_stream_test_
• existing_records() => wp_stream_existing_records()
• stream_query() => wp_stream_query()
• get_stream_meta() => wp_stream_get_meta()
• update_stream_meta() => wp_stream_update_meta()
• stream_toggle_filters => wp_stream_toggle_filters

We need to add stream_toggle_filters to the list.

Damn, somehow I missed that one and it got into the 1.3.1 release. Good eye @lukecarbis

@fjarrett No worries - do you think this 4dc0ca9 is an overkill way to deprecate filters?
