Revert commit 4664677a4e for solarized-dark.reg

* Committ [4664677a4e](https://github.com/neilpa/cmd-colors-solarized/commit/4664677a4eedc25ca1713a42dc43586902e554ae#diff-78deea8aa8cd814c85b0251e6e692668) made zero effective changes to the scheme other than swapping assignments. (Color assignments of color 00 and color 08 were swapped and `ScreenColors` to match the new assignment.
* Reverting this commit ensures identical color palettes for both dark
and light schemes with the only difference that `ScreenColors` and
`PopupColors` are swapped for each scheme
* Cleans up extra line space and extra line in solarized-light.reg so
both files have matched formatting
