Bug fixes; Added readme

That bug where flashText.bottomToCenter would display the text twice.
Another one where I forgot pushStyle() and popStyle()
Readme, refactoring, TextStuff
Selection now from userUI to "actual UI". Introduced PControler class
Added ToDo; minor changes; ready for some refactoring
Major refactoring. Selecting does not work anymore. I'm on a good way
Poses can now be added to PControl elements

e. g.
pControlSchedule.setPose(POSE_LEFT_MID);

also: selection is back
finally ready to bring PControls and mattscheibe together
Finally able to sync this ...
