- modified the GUI in all tools making the text of the buttons bold and adding a new button named Reset Tool which have to reset the tool GUI and variables (need to check all tools to see if happen)

- when the Tool tab is in focus, clicking on canvas will no longer change the focus to Project tab
- Copper Thieving Tool - when creating the pattern platting mask will make a new Gerber object with it
