The API now allows to specify where on the print bed to put the sliced model's center
WIP: Adding option to start printing directly after slicing
Added possibility to say to select or directly a file right after slicing it finished, both to the API and the UI
Removed old printer parameter and appearance settings and added auto migration of config
Fixed URL endpoint for printer profile API, it's supposed to be "api/printerprofiles", not "api/printerProfiles"
Fixed a bug causing the _default profile to be saved to a file instead of config.yaml
Make sure the printer profile fields are all of the correct type during validation
