This commit really helps improve the speed of any action that involves sending
email. It can be improved more and I've been inspired to clean up the email_api
a little more while I'm in here. Stay tuned for more in the next day or so but
it's 4am now so sleep is in order!

• config_defaults_inc.php
  (g_email_receive_own): new config option to control whether users get emails
  about their own actions

• core/email_api.php
  (get_notify_flag): renamed to email_notify_flag()
  (email_collect_recipients): new function to collect the list of users that
  should receive emails but without executing several thousand queries and
  a much cleaner rewrite
  (build_bcc_list):

  • strip down most of it and call the above function
  • use config_get()
    (email_build_bug_message):
  • use config_get()
  • call bug_get_extended_row() instead of executing a query
  • call project_get_field() instead of executing a query
    (get_bug_summary): remove in favour of bug_get_field()
