Currently the screen locker just kills the greeter (kscreenlocker_greet)
when the screen is unlocked by the user during the grace time.
But apparently this can leave behind running screensaver processes
launched by the greeter, see the bug report.
This patch changes this to only terminate the greeter, and adds a signal
handler to the greeter to exit gracefully in this case.
The signal handler exits with return code 1, so that it is not possible
to circumvent the password input by just sending a SIGTERM. (the screen
locker restarts the greeter in case it doesn't quit with exit code 0)

case of immediateLock
If the screen locker is set to not require a password to unlock, it will
not show the password input field even when the powermanagement settings
suspend the system and are set to require a password after resume (when
it was already running at that point).
This locks people out of their system.
This patch adds a signal handler for SIGUSR1 that switches the running
greeter to immediateLock mode. The locker sends that signal to make sure
the greeter shows the password input field when necessary.

* Use QCommandLineParser instead of KCmdLineArgs
* Inherit QApplication instead of KApplication
* Use QCoreApplication::setApplicationName and friends
* Drop k4aboutdata
A new class LogindIntegration is added to the screenlocker. This class
listens to the Lock and Unlock signals emitted by the session object on
the logind service.
This is integrated with the screenlocker application to start or quit the
lock when the signals are emitted. This means a locked screen is unlocked
when the Unlock signal is received from logind. Logind is a higher
authority for the screenlocker and thus follows the requests from logind.

A new Authenticator item is introduced and exported to QML. It provides
a slot tryAuthenticate taking the password as a string. If invoked it
creates a KCheckPass object which handles the communication with the
kcheckpass binary to verify the password. If the authentication succeeded
the Authenticator emits a succeeded() signal, on failure a failed()
signal.
The authentication process is bound to a grace timer. While this timer is
active it's not possible to authenticate again. This state is exposed
with a Q_PROPERTY and used by the UI to disable the password field and
unlock button.
