change owner of ghidra project

ghrab.sh

#!/bin/bash
#
# grab ownership of ghidra project specified in arg1 or current dir if absent
#
#	- looks for the first <projectname>.gpr file
#	- modifies owner name <projectname>/project.prp
#
# example : ./ghrab.sh ~/RE/coolstuff


# Discussed in https://github.com/NationalSecurityAgency/ghidra/issues/5507

# " if you create a project under your current username then try to give it to someone else,
# or otherwise just copy it to another machine or VM with a different user name you will get an error:
# "..Failure to open project ... NoOwnerException: Project is not owned by xxx.."
#
# obvious caveat : this is a bad idea if permissions are not appropriate on some of the project files.
