Bug Fixes in KDE Base
correctly determine input in calculator
The bug reported this behaviour: if you press something like 'a+b+c=',
the result would be incorrect because the calculator plasmoid wrongly
resets the calculator when pressing 'c'. The intended behaviour is that
the calculation is cleared when pressing a number after pressing '='.
This patch adds a variable to determine this situation correctly.
