Following patch will add Time Recurrence features to dialplan module:

- A new column (named timerec varchar 255 not nullable) in dialplan database schema is needed.
- TimeRec value should be compliant to RFC2445 (Internet Calendaring and Scheduling - Core Object Specification) standards in order to match.
- A timerec failed match doesn't stops dialplan rule searching.
- An empty timerec value is not evaluated in rule matching algorithm.
- Attached patch should to be applied to Dialplan Module rev.9282.
