Title: Clear button in PasswordBox, and SelectAllOnFocus property

I added support for the clear button in Password boxes also (it was only partially implemented). I also added an optional property named SelectAllOnFocus, which simply selects all textbox/passwordbox content on initial focus. Thought it might come in handy.
