bluez-obexd (for Bluetooth file transfers in Dolphin)

Description of problem:
after installing a system (at least using XFCE spin), one ends up with a working bluetooth but broken Bluetooth file transfers. There is no user-friendly message to explain what's wrong except for looking into the journal and figuring out how to fix (which is not easy).

To enable file transfers one has to:
sudo dnf install bluez-obexd
systemctl --user start obex
sudo systemctl --global enable obex

I think that `bluez-obexd` should be installed and enabled by default after installing and enabling bluetooth. Otherwise simple bluetooth operations become frustrating for the end user.

Version-Release number of selected component (if applicable):
bluez-5.41-1.fc24.x86_64

How reproducible:
always

Steps to Reproduce:
1. install fedora
2. try file transfer for example using blueman

Actual results:
nothing happens

Expected results:
file starts transferring
