Updated calqlatr demo

Fixes and finetuning of calqlatr demo:
- fixed text overlapping, changed max length of a number from 14 to 9
- fixed app "freeze" after entering number of maximum length
- implemented +/- operator functionality
- fixed listview scrolling, after multiple operations listview was
scrolling only when entering '=' leaving the active line hidden when
the numbers and operator were typed
- added support for entering numbers and certain operators from keyboard
- removed commented code
