Subject: [PATCH] SettingsWindow: Add the ability to add multiple game
 directories at once (#1314)

* SettingsWindow: Add the ability to choose multiple game directories in one go

* Adressed emmauss's suggestion

* Simplified the check for duplicate game directories

As per Xpl0itr's and emmauss's suggestion, I simplified the loop that checks if the selected game directories are already added.

* Fixed a nit
