In these changes, I have added some explanation

of changes to the Set and MSet apps, so people aren't
so shocked and surprised when they upgrade from
1.4 to 1.6.

Also, for the sake of those upgrading from 1.4 to
1.6 with AEL, I provide automatic support for the 
"old" way of using Set(), that still does the
exact same old thing with quotes and backslashes
and so on as 1.4 did, by having AEL compile in the
use of MSet() instead of Set(), everywhere it inserts
this code.

But, if the app_set var is set to 1.6 or higher,
it uses the "new", non-evaluative Set().

This only usually happens if the user manually 
inserts this into the asterisk.conf file, or runs
the "make samples" command.
