Auto complete for Maud #477
Description
It's nice if rust-analyzer could auto complete the elements and attributes. This can be done by setting the "cursor" where the macro is being written in a dumb function that contains some sort of wildcard import like use elements::completion::* and use attributes::completion::*.
