New features

General changes

• Complete rework of the initialization process, folders to be moved are now determined based on the contents of a JSON object.
• Added the ships folder to the profile-specific list
• Various bugfixes

Completely reworked the file structure

• Profiles are now stored under their respective game versions, this allows having multiple KSP versions
• Sock and DLC folders are linked across all profiles from the same version, this means that if there is an update, all of the profile from that version get affected
• All KSP files are stored under their respective version

The new files structure can be seen in the diagram on the wiki

UI updates

• Progress bars are procedurally generated at runtime, adding support for the new folder selection system
• Added a version dropdown to the profile creation menu
