code-style: simplify window title related code

instead of dancing around with some `init` parameter, directly give
`win_set_title()` what it needs. `get_win_title()` now also does *just*
what the name says.

this simplifies things quite a bit and the functions now do what their
name implies more closely instead of doing some `init` dance internally.
