- fixed bug in Geometry Editor that did not allow the copy of geometric elements

- created a new class that holds all the Code Editor functionality and integrated as a Editor in FlatCAM, the location is in flatcamEditors folder
- remade all the functions for view_source, scripts and view_code to use the new TextEditor class; now all the Code Editor tabs are being kept alive, before only one could be in an open state
