Bug: path.path object set in os.environ

[jamoore]

On Windows, objects of type path.path cause the exception below. Therefore, usages like the following should be avoided:

$ git grep -E "os.environ\[.*\].*?=.*?dir"
components/tools/OmeroPy/src/omero/plugins/web.py:        os.environ['ICE_CONFIG'] = self.ctx.dir / "etc" / "ice.config"
components/tools/OmeroPy/src/omero/plugins/web.py:        os.environ['PATH'] = os.environ.get('PATH', '.') + ':' + self.ctx.dir / 'bin'
components/tools/OmeroPy/src/omero/plugins/web.py:        os.environ['ICE_CONFIG'] = self.ctx.dir / "etc" / "ice.config"
components/tools/OmeroPy/src/omero/plugins/web.py:        os.environ['PATH'] = os.environ.get('PATH', '.') + ':' + self.ctx.dir / 'bin'
components/tools/OmeroPy/src/omero/plugins/web.py:            os.environ['ICE_CONFIG'] = self.ctx.dir / "etc" / "ice.config"
components/tools/OmeroPy/src/omero/plugins/web.py:            os.environ['PATH'] = os.environ.get('PATH', '.') + ':' + self.ctx.dir / 'bin'

(In [3e10695c8de9b29ee496b83fca24ecfb79c4e405/ome.git] on branch develop) Wrap path.path objects with str() in plugins/web.py (See #4404, Fix #4451)
