Enhance Call Blocking [master] (#2988)

Browse Source 
* Added support for regular expressions in the numbers to be blocked.
Reduced the caching timeout, as the counter is only incremented when a call is blocked and the number is not cached.

* Added default sort order.

* Added option to switch on/off use of regular expression matching for pgsql and mysql.

* Added support for sqlite and updated default number match to "LIKE" as suggested by MafooUK on IRC.

* Selection of behavior (default [=], regex or like matching) is now done via the variable call_block_matching = regex|like|EMPTY - type text - in the Call Block section of Default Settings.

* Updated comment to match new matching.
