Modeline indicator, background color, readability

[duianto]

The evil-mc modeline indicator, can (depending on the theme) make it impossible or very hard to read.

It looks like this:

• Top: Emacs with evil-mc installed
• Middle: Spacemacs with the spacemacs-dark theme (default)
• Bottom: Spacemacs with the spacemacs-light theme

The background color is the same as the cursors current state color.

In Spacemacs:

• insert state changes the background to Strong green (#66CD00):
  

• visual state changes the background to Gray (#BEBEBE):
  

System info:

evil-mc 0.0.3
Spacemacs 0.200.9

• System 1:
  Emacs 25.1.1
  Windows 10

• System 2: (Virtual box on System 1)
  Emacs 26.0.50
  Ubuntu 16.10

@duianto I think this is also fixed by #64. Is that right?
