Implementation of functional code for log properties page in order to allow user to :
- Make modification and have them taken into account when properties page is closed / apply is used;
- Set defaults (including correction of default max size);
- Delete content of log;
- Make "Apply" button functional based on user inputs;
- Correct default value during installation (duration, size).
- Improve InitPropertiesDlg() error;
- Fix SavePropertiesDlg(): When the event log key does not exist, it is not recreated by the event log viewer.
- GetDisplayNameFileAndID(): Show the error also when opening the event log key fails.
