Increased support for custom recording rules

[derek@…]

The attached patch provides the following functionality to the custom recording schedule module:

* Add more supported recording types
   + Find daily
   + Find weekly
* Allow specification of find day and find time values for custom schedules

Changes by file:
* themes/default/tv/schedules_custom.php
   + Add new schedule options to 'Schedule Options' radio selection
      - Find daily
      - Find weekly
   + Add new section, 'Find Date & Time Options'
      - Allows user to specify day and time for custom rules
* skins/default/tv_schedules_custom.css
   + Added find_date_options id to style sheet for formatting of the new section
* includes/recording_schedules.php
   + The findday and findtime properties were automatically set based on the
     starttime property of the schedule object.  Now, only auto set those values if
     it's not a search based schedule, otherwise use the values received from the
     custom schedule input form
* languages/English.php
   + Added messages under 'modules/tv/schedules_custom.php' section for new content
* modules/tv/schedules_custom.php
   + No longer ignore 'rectype_finddaily' and 'rectype_findweekly' types for custom
     rules
   + Set the findday property of the schedule object to the value from the input form
   + Set the findtime property to the value of the form, if it fits the regex,
     otherwise default to the starttime property
