Create @export_var as alias to @export_

Make the export decorator more explicit and butyfull :)

Sounds good 😀.

It's sad that @export is so perfect but not allowed by javascript.

Maybe @export_any would be a option?

We generate all decorators in PascalCase like @Export as well. See this answer. This should be better :)
