* Prevent FOUC on startup, use Signal Blue instead
Instead of flashing a white background on startup, the app will show a blue background while everything is loading.
* Make sure tests are rendered on white background
* Use `icon_250.png` as the loading image
* Remove hardcoded 'Loading...' text from template
Fix case where db is deleted but password hash still remains which causes user to never register.
Allow password to have symbols and other characters.
Added more tests.
Moved passHash from config into the sqlite db.
We can do this because we assume if sql failed to initialise then the key provided was wrong and thus we can show the user the password page.
