St: Add a StPasswordEntry subclass based on StEntry

Browse Source 
StPasswordEntry will be put to use for password entries
in various shell dialogs. This is done to have a consistent
behaviour for all password entries and introduce a peek
password functionality for these password entries in the
subsequent commits.
