It's a known fact that all the windows in the program should be styled in a same way. I realised that source code view in the program is pretty ugly, so I decided to do something...

- Added some buttons to an empty toolbar
- Added icons to File menu
- Statusbar showing size of document

I also added some preferences for managing Parental Control System filters (Illegal words which activate "PCS banned site").
PCS is currently very simple because it only checks the content of some page and counts how many forbidden words it contains. If there is too much of them, the site is going to be banned and you can't view it before you disable PCS from preferences.

In future I'm going to make many improvements to this system. I have plans to add at least following features:

- Check for well-known pishing sites (Google API)
- Use lists of banned sites
- Make it easier to modify rate of banning
