- in Excellon Editor added a protection for Tool_dia field in case numbers using comma as decimal separator are used. Also added a QDoubleValidator forcing a number with max 4 decimals and from 0.0000 to 9.9999

- in Excellon Editor added a shortcut key 'T' that popup a window allowing to enter a new Tool with the set diameter
- in App added a shortcut key 'T' that popup a windows allowing to enter a new Tool with set diameter only when the Selected tab is on focus and only if a Geometry object is selected
- changed the shortcut key for Transform Tool from 'T' to 'ALT+T'
- fixed bug in Geometry Selected tab that generated error when used tool offset was less than half of either total length or half of total width. Now the app signal the issue with a status bar message
- added Double Validator for the Offset value so only float numbers can be entered.
- in App added a shortcut key 'T' that popup a windows allowing to enter a new Tool with set diameter only when the Tool tab is on focus and only if a NCC Tool or Paint Area Tool object is installed in the Tool Tab
