add quote to User-Name

Hi Alan!

It is a way too complicated for the first sight.

It is Windows based FreeRadius (2.2.10). And user names has a space between
the First and Last Name, so needed to be double quoted otherwise it is
handled as 2 parameters.
(according to my knowledge it is not possible to insert a double quote
between the \" \" sequence which is not deleted by the command interpreter).

exec multiotp {
        wait = yes
        input_pairs = request
        output_pairs = reply
        program = "../../multiotp.exe -base-dir=C:/mutiotp/ -keep-local
-log -debug \"%{Tmp-String-0}\" \"%{User-Password}\""
        shell_escape = yes

Even if I change the User name to a Tmp_String-0 like this the output is
always the user name without the double quotes:
update request {
Tmp-String-0 := "%{User-Name}"

In worst case I'll do the authorization from a small python script where
I'll be able to call the multiotp.exe with the properly quoted user name.

update control {
Auth-Type := `c:\Python27\python.exe %{User-Name}

This is just an experiment - not so important. The main auth server is
3.0.13 - where there is no problem calling the multiotp with user names
containing space.
I presume the 4.0 cannot be compiled on windows.

Thank you!
