Added kdm-fix-resumption-from-console-mode.patch:
* fix resumption from console mode when monotonic clock is in use
(kde#312947, bnc#756198)
- Added screenlocker-always-show-password-dialog-when-needed.patch:
* password input dialog was not shown under certain circumstances
(kde#327947, kde#329076, bnc#864305)
- Added screenlocker-dont-leak-screensaver-processes.patch:
* screensaver processes might keep running in background when
unlocking the screen (kde#224200, bnc#809835)

Please note:
The screenlocker patches are not upstream yet.
The first one is in review at the moment: https://git.reviewboard.kde.org/r/117091/
I want to push the second one as well, but I will do that when the first one is accepted, as it touches the same parts of the code.

I'm using both patches for a week now, they work as expected here, so I decided to submit them now anyway.
