Fix for Bug 927208
Multiple edits needed because of the issues involved with the problem of styling input[type="file"] that are also disabled.
In a nutshell, it's nearly impossible to present input type=file in a consistant manner across browsers platforms. Further complicated by the way Firefox handles those inputs when disabled - text and background-color are given opacity and inherit the parent background color which caused the text to be unreadable on our dark background. So created the .platform class, which is inverse of well.
