Icon requests

[alexcmgit]

Some icons I think would be helpful to have in the set:

• Settings.
• Color palette.
• Reset.
• Power.

I also would like contribute, if you have any doc showing up your guidelines, e.g grid size, what do, what not to do, svg guidelines, etc. it would be really useful, thanks.

Resources I'm already using as base:

• Your figma sketch.
• 

Proposal

These are the initial sketches I'm working on:

• Power icon.

• Reset icon.

• Settings.

• Color palette.

@alexrintt thanks for your PR. Finally had time to go through all the new icon iterations and would like to discuss them first with you if you like them :)
