- fixed a whole load of PyQT signal problems generated by recent changes to the usage of SpinBoxes; added a signal returnPressed for the FCSpinner and for FCDoubleSpinner

- fixed issue in Paint Tool where the first added tool was expected to have a float diameter but it was a string
- updated the translation files to the latest state in the app
