Improve general customization

Figure out the correct flow

• All components should have the global vui CSS variables localized. So basically --text-size in button will be --button-text-size and will be using the global text-size as default value
• Make sure that inline style attributes and classes provided by the user will override any kind of vui-provided styling
• Make sure all components have this implemented the same way via audit

I wish I could hire someone to do this I so don't feel like doing this 😿

Some small progress was done in #61 by adding 3 local CSS variables within Badge.
