The Database, DatabaseWidget, and DatabaseTabWidget classes share many responsibilities in inconsistent ways resulting in impenetrable and unmaintainable code and a diverse set of bugs and architecture restrictions. This patch reworks the architecture, responsibilities of, and dependencies between these classes. The core changes are: * Move loading and saving logic from widgets into the Database class * Get rid of the DatabaseManagerStruct and move all the information contained in it into the Database * Let database objects keep track of modifications and dirty/clean state instead of handing this to external widgets * Move GUI interactions for loading and saving from the DatabaseTabWidget into the DatabaseWidget (resolves #2494 as a side-effect) * Heavily clean up DatabaseTabWidget and degrade it to a slightly glorified QTabWidget * Use QSharedPointers for all Database objects * Remove the modifiedImmediate signal and replace it with a markAsModified() method * Implement proper tabName() method instead of reading back titles from GUI widgets (resolves #1389 and its duplicates #2146 #855) * Fix unwanted AES-KDF downgrade if database uses Argon2 and has CustomData * Improve code This patch is also the first major step towards solving issues #476 and #2322.
