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.

I'm having trouble with AEL in 1.6.x and trunk, because the underlying
behavior has changed, and the automatic stripping of quoted strings is no
longer taking place because the AST_NONSTANDARD_APP_ARGS() macro is not
being used to split up
the args. 

Hmmm. It occurs to me that one solution to this problem is to 
use MSet instead in the generated code of AEL, to preserve the previous
behavior. This would lock in AEL, though, to forever
use the old behavior. The app_set stuff in asterisk.conf is the alternate,
but it's surprising upgrading users who fresh install asterisk 1.6.x and
get the 1.6 behavior.
