add support for async methods in component

[Fille]

I dont know how to add it myself, so adding this as a requested feature or if you could give me a hint how to add it myself. any nice resource to learn this?

right know it looks like this, would be nice to have it colored as in regular js files

i just realize that this probably cannot be done through this package, i guess it has to be supported in the grammar package, perhaps language-babel or something
