Convertor.php Improvements (remove relative paths, dependencies...)

K - below are Michal requirements and suggestions. If you feel there is a better way to meet his needs - please hook up w/ him and discuss...
--------------------
Sandboxes infrastructure uses distmaker script heavily for building
tarballs, but also for generating PHP4 code. I just realised some of the
problems users have with tarballs might come out of the fact, that
bin/converter.php is out of synch with distmaker/utils/converter.php
script. Can someone please do the following with bin/converter.sh
script:
a) fix the dependency on config file path:
require_once "$homeDir/svn/crm/modules/config.inc.php";
The path to svn root dir should be passed as a first parameter.
b) fix relative path calls
c) fix the hardcoded generated files target dir path (s/b also a
parameter)

The goal would be to call the converter script from anywhere (like
"php ../../bin/converter.php PATH1 PATH2") and it still did it's work
properly. After those fixes are introduced, let's move converter.php to
distmaker's directory to keep only one version of the file.
