CSS rule filter: invert() creates error message

[MJH1000]

`Sass Compiling Error

style.scss
"Missing argument $color: style.scss on line 931, at column 1"`

SOLUTION:
Make the SASS compiler case sensitive to process only lowercase so filter: INVERT() gets ignored by sass and can be used as css

This plugin uses the ScssPHP compiler we are on version 1.5.2, they have since moved up to 1.8.1
It could be that your request is part of a newer version. You could take a look at upgrading this if you want.

We are upgrading to v1.10 in #233 you can pull that branch down to test if that will fix this.
