Summary:                    Can't add 0 in front of function result within if()
block of AEL
Description: 
I'm trying to construct syntax that will allow to use function result
directly in mathematical expression, and in case if function result is
empty (NULL), interpret that as 0. This works fine from .conf file or
realtime table:

Set(calls_missed_queue=$[0${DB(agent_globals/${target_num}/calls_missed_queue_${call_from_queue})}+1])

Here's the line from AEL that doesn't work:

if
(${GROUP_COUNT(${target_num}@agent_queue_b)}=1+0${DB(skip_group/${target_num}/agent_queue_b)});

Seems that there's no way how to use this within if() check directly, it
returns error at AEL compile time ("aelparse -d -n -w -q extensions.ael")

(closes issue http://bugs.digium.com/view.php?id=12467)
Reported by: atis
Tested by: murf

This upgrade adds the ~~ (concatenation) string operator to expr2.
While not needed in normal runtime pbx operation, it is needed when
raw exprs are being syntax checked. This plays into future syntax-
unification plans. By permission of atis, this addition in trunk 
and the reason of why things are as they are will suffice to close
this bug.
