Add components

[estevanmaito]

Components that exist in the React version but not here:

• Link Buttons
• Outline Buttons

The introduction of these button styles also affect inputs with buttons, icon buttons, tables with actions, dropdowns, you got it, I add 1 button and the entire application collapses. It's scary how sometimes web development resembles people's emotions.

General improvements:

• Check text color across labels, headings and paragraph text.
• Remove search input background
