user services: Rework the way ceres services are launched in a cleaner systemd-wide way. This also makes those recipes less asteroid-spcecific for systems with a different username.

Replace ttf-opensans, ttf-orbitron, ttf-raleway, ttf-roboto and ttf-symbola with ttf-asteroid-fonts which centralizes those fonts and many more

asteroid-launcher: Export QT_IM_MODULE to make sur BluetoothAgent.qml finds QtVirtualKeyboard and instanciates correctly

Make sure user services are only run as ceres. Since openssh uses pam login, ssh root@watchIp would open a new systemd user session and start asteroid-launcher or other services as root

asteroid-launcher: Don't disable input on qemu to solve http://blog.livedoor.jp/furikku9310/archives/52491266.html

Adds a recipe for ttf-orbitron and makes asteroid-launcher depend on it for the new scific watchface

Adds a recipe for ttf-raleway and makes asteroid-launcher depend on it for the new default watchface

Adds a recipe for ttf-roboto and makes asteroid-launcher depend on it for the upcoming default watchface

Now that we use meta-qt5's jethro branch, libconnman-qt5 is provided so we don't have to maintain libconnman-qt anymore (also fixes an asteroid-launcher warning message about MeeGo.Connman)

android-init, asteroid-launcher, glacier-home: install .service in /lib/systemd/system instead of /etc/systemd/system
