Fuse-box: Allowing fuse-box-css module on Server

[leon-andria]

For SSR, it should be good to have fuse-box-css module available rather than having error message that this module is not available.

this module is "working" on server. It's not reporting errors

[devmondo]

it is important to mention that this module needs to be added to the arithmetic instructions on the server bundle to remove the error above.

@devmondo How does one do that?

@JohnLouderback for example fuse.bundle("app").instructions("> index.ts + fuse-box-css")
