#29: Streamline the Ultet processing

[benedeki]

The process is now:

• initialization
• source code analysis and creating the db app model
• target database(s) analysis, and update of the DbAppModel with it.
• DbItems (diffs) generation for each database and grouping them per transaction
• SQLs generation from DbItems
• execution/print of the SQLs

Other chances:

• Using Balta for queries now
• Multiple databases (in source only) support
• Finished and refactored table diffing

Depends on #13

Partially solved for #8

Closes #29 Closes #12 Closes #6
