Removed the need for entity specific form classes. Now it is enough to
initialize Form with desited entity object and all the functionality is
available
Formatted code, added logging after successful SQL, moved getAll to 
ORM class, so theres usually no need for entity specific services.
service attribute moved to Page class, added entity attribute and
abstract method for setting it, moved addAction method to Page since it
is rather generic, code formatting
Fixed multiple message setting scenario when first message was a real 
message, other element was false and so 2 messages were sent to HTML
