Add Fluent to syntax highlighting

This is a request to add the Fluent language to the built-in syntax highlighting.

Example:

```fluent
# Simple things are simple.
hello-user = Hello, {$userName}!

# Complex things are possible.
shared-photos =
    {$userName} {$photoCount ->
        [one] added a new photo
       *[other] added {$photoCount} new photos
    } to {$userGender ->
        [male] his stream
        [female] her stream
       *[other] their stream
    }
```
