Consistent matching and selecting colors over modes

[cryon]

As it it right now the matching and selecting of lines differs quite a lot between modes.

Make the theme more consistent by inheriting the same colors for selecting lines and matching results over ido, helm, company etc..

Regarding to selection, a new slightly brighter "midnight" color should be added that can be used as background color for highlighted selections/rows. The background need to be tested against all other defined foreground colors, if necessary use :distant-foreground.
