Database: Possible optimalization

[jzych]

Probably this can be done in one line: addPerson(new Student(data));

CS_Database/src/Database.cpp

Lines 92 to 93 in 4833021

	Person* person = new Employee(data);
	addPerson(person);

CS_Database/src/Database.cpp

Lines 97 to 98 in 4833021

	Person* person = new Student(data);
	addPerson(person);

It can. But how to prevent memory leaks? :)
