Calculator gets increasingly slower with long calculations

The root cause of problem was that whole formula is calculated every time.
This bug is duplicate of the:
https://bugs.launchpad.net/ubuntu-calculator-app/+bug/1315799

this makes the app unusable, how can it be medium?

Fix committed into lp:ubuntu-calculator-app at revision 289, scheduled for release in ubuntu-calculator-app, milestone 1.6

Thanks Riccardo for your hard work.
Unfortunately slowdown still exists (please try to press "=" repeatedly).

I already fixed slowdown (see branch), but there are also several regressions:
1. Unable to change sign of the result
2. The error: file:///home/a/dev/core/ubuntu-calculator-app/engine.js:359: Too long number is displayed with a long number
3. Backspace is not working correclty (it doesn't delete last char)
4. Scanner is not working correctly for single number (formula.js)
