Summary:                    AEL does not translate quoted strings correctly in
1.6
Description: 
I used to use constructs like 

    a = "test here";

in the Asterisk AEL scripts. These were working fine in 1.4 (translating
to)

    Set(a=$[ "test here"])

This does not work for 1.6 anymore although translates to exactly the same
dialplan. After executing this line the value of a variable on 1.6 contains
quotes.

This results in:
1. The following construct:

    b = "${a}";
does not work at all giving parse error [Aug  6 18:01:24] WARNING[29514]:
ast_expr2.fl:437 ast_yyerror: ast_yyerror():  syntax error: syntax error,
unexpected '<token>', expecting $end; Input:

2. when the variable being assigned is CALLERID(number) - this results in
sending 

    From: ""test here"" <sip:xxxxxxxxxxx at 1.2.3.4>;tag=as1539ede1

in the SIP INVITE header. Note the double quotes. As result, the Aastra
57i phone rejects the invite with 400 Bad Request.

---------------------------------------------------------------------- 
OK, I did update AEL to check for this type of situation and issue a
warning at runtime, as AEL is loading and parsing the dialplan. The
standalones won't do because they don't load asterisk.conf; however, if
there is sufficient demand, I can update the AEL standalone tools
(aelparse) to load asterisk.conf and determine if this is a possible
problem situation and issue the warning also.

See revs 138815 & 138845 in trunk; 138846 and 138847 in 1.6.0, and 138853
and 138855 in 1.6.1
