[PD] close all patches on quit sourceforge patch

[Hans-Christoph Steiner]

Hmm, something different, but still not running:

hans at palatschinken bin $ cp ../src/pd.tk .
hans at palatschinken bin $ ./pd-l2ork -stderr -d 3
set pd_whichmidiapi 2
pdtk_pd_startup {Pd version 0.42-6extended-l2ork-20121007
} { {OSS 2} {ALSA 1} } { {default-MIDI 2} {ALSA-MIDI 1} } {DejaVu Sans Mono}
normal
set pd_whichmidiapi 2
tcl: /media/share/code/pd-l2ork/pd/bin/pd.tk: can't open script
^CPd: signal 2
hans at palatschinken bin $ ls -l /media/share/code/pd-l2ork/pd/bin/pd.tk
-rwxr-xr-x 1 hans hans 289074 Oct 24 23:55 /media/share/code/pd-l2ork/pd/bin/pd.tk
