This patch resolves the following problems:
1. (Hopefully) correct handling of all files names (incl. drive characters and '!' in file names).
2. The neccessary trailing slashes (necessary for Nokia 6670 and Siemens C65V).

Usage:
Download the patch from: http://www.tech-edv.co.at/downloads/obexpatch-0.31.1.tgz
Save the current version of the files $OBEXTOOL/lib/obexfile.tcl and $OBEXTOOL/lib/obextree.tcl - they will be overwritten by this procedure.
Unpack obexpatch-0.31.1.tgz in the ObexTool main directory - eg:
cd $OBEXTOOL
tar -xzvf obexpatch-0.31.1.tgz
Warning: the existing files lib/obexfile.tcl and lib/obextree.tcl will be overwritten!
Restart ObexTool...
