Change exec_command of history_manager.py
I attached a patch by Vlad Glagolev, sent to ports@openbsd.org while updating Gajim to 0.11.2
On OpenBSD there is no /usr/local/bin/python by default, only /usr/local/bin/python2.X, where X is the minor version. So unless you didn't create a symlink for /usr/local/bin/python
helpers.exec_command('python history_manager.py &')
get's you an error.
The attached diff fixes this.
