Use AppData für settings

[larsen0815]

Settings folder should be "%userprofile%\AppData\Roaming\SuperXPutty" instead of "%userprofile%\Documents\SuperXPuTTY".

Should be created (ask user) if it does not exist instead of showing "must be set to valid directory".
Pressing ESC there should only close the warning message not the whole setup dialog.

The Documents folder was deliberately choosen as it is backed up by OneDrive, so you never lose your settings or sessions when you switch PCs, and it is easy to share the sessions xml from there to other co-workers.

If you want to save the settings to AppData, you can change this path in the settings.

Will look into optimizing the behaviour on error.

Not so useful when you don't use OneDrive ;-)
