Demo Video: https://www.youtube.com/watch?v=4EM2_lW2S54

Major Changes:

• Now user can select one or more folders to display on the home page.
• Added Refresh button to the home page as well as videos page to delete the Tauri cache and reload the page (useful when user adds or removes something from the folder and wants it to update)
• In the settings page, the user can control which folders to keep and which to remove.
• When a user removes a folder from the settings page, the thumbnails in that folder are also deleted
• When a user tries to add a folder which is already present, the user is shown an error.

Minor Bug Fixes:

• Fixed the sorting function for arranging in alphabetical order
• Album Error handling issues are fixed. Now duplicate album errors are shown like in previous versions.
