Add support for SSR/SSG

[lukasmatta]

Once fix for angular/angular-cli#27590 is published (should be the next patch version as the fix PR is already merged) we will need to update @angular/angular-cli package.

Note that CpsDivider was removed as it does not support SSR (it is accessing document directly - _dividerColor -> getCSSColor -> isValidCSSColor -> document.createElement on colors-utils.ts:13)

So basically isValidCSSColor is a fundamental library function, we need to reimplement it using color-name to check css named colors and regular expressions for verifying other formats.

I think it should be enough to just not use global document object and use Document from DI instead

This will also work, but we need to pass it
