Bug with f:convertDateTime. It has timezone issues displaying dates as
the day before and so it was replaced by s:convertDateTime who works
correctly.
Just correcting some spelling mistakes.
gh-89:Now with each Employee insertion the following information is also
recorded
* An EmployeeInfo row is added for each Employee inserted
* An NonRegularEmploymentInfo row is added for each DEPUTY or HOURLYPAID
Employment inserted

**UI Changes**
* Redesigned the _Καρτέλα Εργαζομένου_, particularly the _Basic Info_
container and 'tab-ified' its contents into _Βασικά Στοιχεία_,
_Συμπληρωματικά Στοιχεία_, _Στοιχεία Μονίμου_ & _Στοιχεία Εργασίας_.
* Redesigned the new Employee addition process allowing the insertion of
not only REGULAR but also DEPUTY and HOURLYPAID employees.
* Added a _Διαχείριση Στοιχείων Μισθοδοσίας_ sum-menu link under
_Διαχείριση Εργαζόμενου_ when in _Καρτελα Εργαζομένου_.
* In _Καρτελα Εργαζομένου_ in the table _Προγενέστερες Τοποθετήσεις
Εκπαιδευτικού_ added more columns (Έως/Πράξη Ανάληψης/Ημερομηνία Πράξης
Ανάληψης).
* Reviewed and synced input textfields' maxlength with the length of
their respective DB table columns.
* Also now when an information field is null or empty, 'null' does not
appear in the UI.

Various Spelling mistakes

Hours_ are copied to _Final Working Hours_
