Subject: kwebapp improvements

- added password widget
- improved contextual menus
- added rekonq statusbar messages

There are a lot of changes here, but they are quite safe
as the code is somewhat duplicated by the original classes in rekonq

I know the situation is suboptimal, but we need to wait for next
development period to properly fix it
