V1.1

[Mysterken]

This PR will change the project structure so that the actual code is located under /source, it was also "cleaned" by using IntelliJ "Reformat and Cleanup Code".

Notable changes:

• There is an option to search a game from all categories at once which is now the default.
• The logo of the plugin is now the DLsite logo instead of a generic one.
• The README has been updated to include a guide to directly get metadata from the game page.
• The dependencies have been upgraded.
