Enable use of mixins

[turboteddy]

Based on comment by @Kocal , I experimented a little bit. I have now knowledge of the inner workings of jsDoc, so this is just a "nudge to look in the right direction".

Works with code like this

/**  * Description   * @mixin someMixin  * @vue-computed {*} comp1 DOCUMENT ME!  * @vue-computed {*} comp2 DOCUMENT ME!  */ export default { computed: { ...mapGetters([ 'comp1', 'comp2' ]) }, methods: { /**  * DOCUMENT ME!  * @param a  * @param b=null  * @returns {*}  */ foo(a,b=null) { //.... } } };

...and corresponding module that uses this mixin:

/**  * Description  * @module components/someModule  * @mixies someMixin  * @vue-computed {*} comp3 DOCUMENT ME!  * @vue-computed {*} comp4 DOCUMENT ME!  */ export default { name: 'someModuleName', mixins: [LanguageKeysMixin] // .... };

However, this hack needs to be improved upon, because...

• Only mixins with componentName ending with "Mixin" work
• name of mixin cannot be prefixed with "something/"

Also, it would be nice to have the members that have been mixed into module components/someModule to be displayed for that module.
