various Metrics.ini and en.ini cleanup

Changed "SpeedNew" to "SpeedModNew."  Made it translatable in Metrics.

Various fixes for better 4:3 aspect ratio support in PlayerOptions and
PlayerOptions2.

Deleted various unneeded metrics.

Revert the changes of commit 28400b7aebf2c57980fec00ddd82f246c43af4fa
by restoring LineSpacing in _misoreg hires.ini to be 24, and use
negative vertspacing where necessary (various OptionRows).

There is still more cleanup to do.
