Ignore #colorLiteral for line length

[Juice805]

In Xcode 8 there is the ability to directly input a color from a swatch picker in the editor. In Xcode it simply shows a colored square, however the actual code is:
#colorLiteral(red: 0.2431372549, green: 0.6431372549, blue: 0.6823529412, alpha: 1)

this often trips the line_length rule. Is there a way to configure SwiftLint to ignore specifically this bit without individually marking each occurrence? I would also like to suggest this rule to be a default.

One thought would be to "remove" #colorLiteral(.*?) from every Line in LineLengthRule.validateFile(_:).

SwiftLint/Source/SwiftLintFramework/Rules/LineLengthRule.swift

Line 28 in ecbba04

public func validateFile(file: File) -> [StyleViolation] {

Now that #830 was merged, I think this can be closed
