Add search feature to the app store

[AaronDewes]

As the app store grows, a search feature should make using it much easier. This uses fuse.js, so it doesn't search for exact matches, but allows for small differences.

Very nice, this was much needed. I'm not a fan of the full-width text field though. Just as a small suggestion, we can wrap the input in a column grid to make it smaller.

<b-row>
  <b-col cols="4"
    ><b-input
      v-model="searchQuery"
      class="neu-input my-4"
      placeholder="Search for apps"
      type="text"
      size="lg"
      autofocus
    ></b-input
  ></b-col>
  <b-col></b-col>
  <b-col></b-col>
</b-row>

I kind of agree with Phil that the input is too big. I would probably just put a max width on it on desktop, and keep it full width on mobile. I don't care enough to reject this though so Ima approve this. Great work as always guys! Ya'll are killing it @pwltr @AaronDewes !!! 🚀🚀🚀

Merging now, we can redesign later.
