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
}
```
