Unable to register class method as template stack location

[johnjamesjacoby]

In bp_register_template_stack() the function_exists() check is preventing class methods from being used as a callback.

In 8461:

In bp_register_template_stack() wrap function_exists() check with is_array() check. Allows class methods to be used as a callback for adding new template stack locations. Fixes #5671.

In 8462:

In bp_deregister_template_stack() wrap function_exists() check with is_array() check. Allows class methods to be removed from template stack locations. See #5671.

Best is probably to use is_callable(). Then indiscriminate arrays won't be allowed through, and you only have to do a single check for all PHP callable types.

In 8463:

Replace function_exists() checks with is_callable() in template stack functions. Props boonebgorges. See: #5671

Duh. Thanks for this. Much nicer.
