Create colorpicker module

[RKBoss6]

Creates colorpicker module as an easy way for apps to present users with a color selection menu.
I've been wanting a menu that could do this for a while, as the alternative before was to make a scroll menu with all the colors and have the users scroll through all of them, instead of being able to see them at a glance. Currently this only works on bangle.js 2, I'm not exactly sure how to convert it to bangle.js 1 as well. This can be used in places like clock_bg, where users need to select multiple colors, or even in the theme menu and other system-level places if the need arises.

This is my first module, so let me know if I need to do anything else or did something wrong :)

Single color mode:

Multi-select mode:

You can look at an example implementation in the Clock Background app on my app loader, and just upload the module to your watch as colorpicker via web ide.

For bangle.js 1 compatibility, would the best course of action be to make the up/down buttons change the highlighted color, then a select is used to select it?

Alright, this is good to go now :)

Nice idea, seems useful

There's a few mistakes that feel like they're a bit sloppy, is it from an AI or just some changes later on made only in one place?

[RKBoss6]

Ah - I didn't use ai, that was just me making silly mistakes :) I'll get to fixing these, but no promises when as I'll be on vacation this week

[bobrippling]

No worries, thanks for your honesty - let me know if anything isn't clear / if my comments could be more helpful :) And enjoy your vacation!

I think all your suggestions are added now. The only thing left is bangle.js 1 support. Also, I don't need to add the module to a list or anything like that for it to be pulled in through the app loader, right?

Maybe a possible Bangle.js 1 implementation/placeholder could be a showmenu menu with all options?

No opinion on if you need to make it from me though 😺

Thanks, LGTM! I think we leave BJS1 support for another PR :)

Not to be pulled through - what you have will work well. I can't find it so I think I might have made it up, I don't think there's anything on banglejs.com that would need updating either. Will merge if you're happy @thyttan?
