Arguments from desktop entry are broken up

[Vladimir-csp]

Hi!
Testing uwsm integration via a desktop entry, I have this line in /usr/share/wayland-sessions/sway-uwsm.desktop:

Exec=uwsm start -N Sway -C "An i3-compatible Wayland compositor" sway

It fails with "i3-compatible" is not in PATH!, which means that "An i3-compatible Wayland compositor" argument was broken up.

    ├─session-147.scope
    │ ├─1567388 /usr/bin/emptty --daemon --tty tty8 --config /etc/emptty/conf-tty8
    │ ├─1567437 /usr/bin/python3 /usr/bin/uwsm start -N Sway -C "\"An_i3-compatible_Wayland_compositor\"" sway
    │ └─1567451 systemctl --user start --wait [email protected]

Quote handling seems to be missing.

Hi,
you are right, there is very basic way for handling of Exec and it was simple split by space, which is insufficient for given example. Please, review changeset.

It won't cover the whole spec, but at least simple quoted arguments would work, which would probably be sufficient for most wayland-sessions cases.

The specifications are meant for desktop applications, for DEs/WMs it's overkill.
