ALF-7260: schema comparator - improved language of reporting.

The differences and validation messages are hopefully improved, e.g:

Difference: missing sequence from database, expected at path: .alf_acl_member_seq
Difference: missing table from database, expected at path: .alf_acl_change_set
Validation: index alfresco.some_table.idx_table_id.name="idx_table_id" fails to match rule: value must be 'xyz'

I'm sure there's still room for improvement but this should give a decent starting point.
