Feature request: More color options

I'm suggesting/requesting a bunch of stuff at once here.

I noticed that there is a currently working tag that makes the text rainbow (color=rainbow), and it's used for a few random textboxes.
Black and white are colors that are available on all color tabs.
Sometimes text coloring gets messed up in a way that makes only the first character be colored and everything else is white. (honest example (copied from debug): color=#00ff00 H text=join color=white eya)

What I'm suggesting/requesting is:

• add a way to use rainbow-colored text in the textbox generator (like adding that option in the special colors tab of the color picker)


• maybe remove black and white from the special colors tab in the color picker? they're already present in the other color tabs anyways


• maybe add a "apply to text" button next to the the "apply to selection" button for text color, so the whole text is colored and not just a portion of it (would be like putting the color tag before the text and not putting a color=white tag at the end)
