Misc send.inc issues

FUNCTION _send_submit()
- typo [if(!count($recipietns)) {]

FUNCTION _send_settings_form()
- shouldn't call to module_invoke($m,'send', 'settings', $m) reference $module, not $m? or am i missing something?
- think there needs to be a check on return value of module_invoke before calling array_merge, or a cast of the module_invoke return value in the array_merge call

i don't know how to make a patch yet, else i would just be providing it ....

thanks for this module, and for the 4.7 updates.
