Clean up interface/changing of settings/additional settings, etc.

[syncore]

TODO:

• Remove 2nd password field, since account info is verified with Bethesda & user will know when saving settings whether the password was incorrect
• Automatically delete data.qcl file when an incompatible version is detected (i.e. when upgrading to a new release) instead of showing message, since it might be confusing
• Add FPS limit to interface (instead of using shortcut)
• Add ability to easily change settings / saved account directly from UI without having to delete data.qcl file
• Add additional experimental settings
• Add ability to clear settings on authentication errors
• Improve QC update checking (wrong to assume that executable hash will differ; not always the case, i.e. QC hotfix updates)

Status update: I did not forget about the tasks above, but have been busy with other commitments. The work in this Issue is almost complete. Expect a new release in the next few days.
