Using custom vue components

[WillGoldstein]

Is your feature request related to a problem? Please describe.
Sort of - if you try to import a vue component in the config, you get an error on load saying:

Uncaught SyntaxError: Unexpected token <

which is happening to me because my vue component in question has a <template> tag.

Describe the solution you'd like
Similar to Larecipe, it would be awesome if you could import your own vue components. In this particular case, I think the sidebar is best used to have a way for users to sign up to a newsletter. I can rebuild it all to work within the context of sidebar.blade.php, but I'd rather have one component/code base to manage for newsletter sign ups.

Describe alternatives you've considered
None really, except copy pasta code.
