Document Common Component helpers classes

[joseegm]

goal: We need a page on the component page to document all the helpers that we have right now.

Tasks

• [ ] List all current helpers and the usage, separated by category: spacing, margin, font-size, alignment, etc.
• [ ] Document all in a new Component page on the website.

@xak Can you provide with a list of those helpers, or maybe they are all in the same .scss file?

[xak]

They are all compiled into dist/helpers

See #1085 for additional needs.
