Get rid of Game::savearea (std::string)

This is what got saved to the area part of the <summary> tags, and it
was specifically set upon pressing ACTION to save in the map menu.
Which meant tsave.vvv may not get an accurate area name (notably
"nowhere" if you hadn't quicksaved before in that session) even though
it's not displayed anywhere so it didn't really matter. But this
variable can be removed - there's only one place where <summary> is
written for both quicksaves and telesaves, so that now gets the area
at saving time.

Fun fact: custom level quicksaves also have a <summary> tag, and it's
even less functional than the one in tsave.vvv, because it stores
whatever main-game area name applies to your current coordinates.
So I simply filled in the level's name instead (just like what the
actual save box says).
