Completed the TDE/ patches & worked on READMEs:

- Renamed the 'ksysguardd' patch so that it contains the TDE version number
  that it should be applied against.
- Added build-instructions for the custom 'ksysguardd'.
  + Added the 'cmake-trinity-setup' file to help others trying to build.
    (I use this script file myself.  So, it's good to have it committed
    someplace online just for my own sake.)
- Tweaked the 'ksensors' README.
