[Unattended] New appsonly.bat in the SVN, changed the way of detecting already installed Perl

[Gerhard Hofmann]

Hi all,

I have updated appsonly.bat in the SVN.

Only a small change: in the past, I have checked for an already existing
Perl installation like this:
...
if exist %SystemDrive%\perl\bin\perl.exe goto runperlscript
call %z%\scripts\perl.bat
...


Now:
...
assoc | find ".pl=Perl" > NUL
if errorlevel 1 call %z%\scripts\perl.bat
if errorlevel 0 goto runperlscript
...

That should detect an already installed Perl no matter which path it was
installed to.

Regards
Gerhard
