Color fading isn't working correctly

[rm-code]

Whenever a file is modified its color is changed to the respective modifier-color. The color is then supposed to fade to the original color.

Sometimes files will reset their colors too fast. It's a minor issue but noticeable.

Looks like this happens because we currently "reset" the color after a certain amount of time. Lerping might be the wrong approach here anyway.

Should be fixed as of 67a5ec8 since I got rid of the color timer.
