This is version 0.7.6
- Close button moved to tab to prevent accidental closing of tabs (curve selector was close to x-button)
- Bugfix: Global fit did not display weights correctly
- Bugfix: Average for one curve has zeros as SD. Division by zero error.
          Solved this by removing the SD in such a case.
- Bugfix: Simulation did only work if a page change occured. Added call to corresponding function on __init__
- Updated Changelog.
