Change where the program looks for the settings file

Currently it looks inside the .encryptext folder in the current user's home directory. This means that if the user moves it to a different computer with Encryptext also installed there, it could accidentally take their settings and show their recent files.

Because we know where the exe is, we can check its path relative to the file rather than the absolute path that changes based on the user's username.
