Set :inverse-video on mode-line to nil in respectful theme

#### Summary

When using Sellout's Solarized Dark theme on Emacs Version 24.3 (9.0) on OSX with smart-mode-line-respectful-theme, there were some light grey 'fill'-faces as seen in #87. I noticed that in #87 this problem was fixed for the dark-theme and light-theme with commit 9ec3ef82d95c842548ef098ee4dfe56f4ad4d35c, but I did not see any changes pertaining to respectful-theme.

#### Changes

I set :inverse-video to nil for mode-line in smart-mode-line-respectful-theme.el.
