Feature request: option to change CSS class root from ".fa" to something else

[jakes-space]

Is your feature request related to a problem?

I added Font Awesome to my web app ... and all my floating action buttons (CSS class .fab) broke.

An option to change the prefix of all Font Awesome classes would help avoid name collisions for existing projects.

Feature description

A kit option to change the prefix of all Font Awesome CSS classes.

If the developer sets it to "foobaz", then all classes within that kit start with .foobaz:
.fa → .foobaz
.fa-face-smile → .foobaz-face-smile
etc.

Alternatives

• Rename my classes to avoid collisions.
• Use the SVG files or strings but not the core FA package and its styling.
• Use the JS API's cssPrefix option to change the prefix. Probably the best current solution, but requires JS.
