Fix up CursorLineNr

After the previous fixes, the CursorLineNr was a bit too dark.
The dark colour could be seen with:

set cursorline
set number

This change aligns the CursorLineNr with the old look-and-feel and
fine-tunes it to also be slightly duller than before. The change applies
both to the UI and console colors.

Bump up the version number

As of now taking the version number up is manually done like in this
commit. The number itself is for the benefit of people who do not see
the git history.
