[Feature]: Delete project folder support and merge Recents Projects with open existing project

[UnknownKing407]

• the close button in Recents Projects is not deleting the project folder, is just hide the project from ide
  pls make it delete the project folder just like in the older version

• also why Recents Projects is not merged with Open existing project, just like in old AndroidCS
  pls restore it, and to open and select another folder (Not in /storage/emulated/0/AndroidCSProjects), you can add "import" button just like the old version
