Saving of Locallab tool parameters in .pp3 file

- Control spot panel parameters are now saved in .pp3 file
- Control spot curved are now visible when Locallab tool panel is
active, not visible otherwise

Limitations:
- Other Locallab tool parameters aren't saved in .pp3 file yet
- Locallab tools are temporary deactivated (time to end procparam
update)
