Settings directory has changed, breaks user settings

[njhanley]

Release 1.2.0 changed the settings database directory from ~/.local/share/cool-retro-term/QML/OfflineStorage/Databases to ~/.local/share/cool-retro-term/cool-retro-term/QML/OfflineStorage/Databases, breaking existing user settings.

I'm not familiar with Qt but this line appears to cause the change. It was added in commit dae1a56. https://github.com/Swordfish90/cool-retro-term/blob/74ae511f923a7c42274086f9b9959e2292d74ddc/app/main.cpp#L85

Observed on Arch Linux with package cool-retro-term 1.2.0-2.
