* Use shortcuts for switching zoom mode.
* Change indent in diagr.cpp (I should have done that in an additional commit )
* Don't show the label "0" at the point (0;0) as it don't work in some cases + it looks messy with too many labels.
* Show the axis correct.
* Always show the  "x" and "y"-labels.
* Don't put labels over other labels.
* Ability to stop a preview drawing by clicking on the graph widget. That doesn't worked before as the fdlg-dialog is modal.
* The trace-switching function with the keys is rewritten. This time it looks much  cleaner.
* Use a lower precision for numeric integral calculations.
* It's not necessary .
* Don't mess up everything when resizing the window during a drawing.
* Optimize the drawing a bit as we don't set pen style every time x increases any more :-)
* Declared some variables as consts.
* Use a wait cursor when the program is drawing.
* Don't do areaDraw=false; every time the functions are updated, it's not necessary anymore.
* Clear the "y"-textbox when opening the Get-Y-Value-tool.
* In kparametereditor.cpp: Don't import empty lines.
* Now you can draw integrals with both xmin and xmax <0.
* Clear the "root"-column when leaving trace mode.
* You can now stop a drawing by pressing any key.

I hope I didn't forgot anything :-)
