flatpak 1.0.2 release.

• The dbus proxy is now available in a separate git module, xdg-dbus-portal, which is imported into flatpak as a submodule. It is possible to build flatpak against the system xdg-dbus-portal instead, but this is not currently very useful as no other applications yet depend on xdg-dbus-portal.
• Build regressions with older versions of glib have been fixed.
• Flatpak ps now also tracks the pid the main process inside the sandbox.
• Added flatpak override --reset to reset overrides for an app.
• Added flatpak override --show to show overrides for an app.
• flatpak install now automatically pick user or system based on the remote name given (unless the remote exists in both).
• flatpak uninstall --unused now does not remove SDKs if some installed app refers to them.
• Fixed bug where flatpak uninstall --unused prompted for uninstall twice.
• Set IO class on the system helper to "idle", which should cause backgroun updates to affect the system less.
• Fixed regression in flatpak uninstall --no-related.
• Better handling of empty collection ids in flatpak bundles.
• Cleaned up some error messages.
• Various documentation fixes and cleanups.
• Updated translations.
