Migrate hardcoded page data to archive/vue data

[GiovanH]

Data that's hardcoded that really shouldn't be.

Page attributes that should be in the page data:

• [x] Scratch page banners
• [ ] Other page banners (collide, act7, trickster)
• [ ] Basically everything in MediaEmbed.data
• [x] Next page number (optional, defaults to n + 1)
• [x] Passwords
  • Page.vue nextPagesArray
  • TzPassword.vue

Other hardcoded data:

• [ ] Home screen cards
• [x] Setting descriptions
• [ ] SBAHJ comic "navigation"
• [ ] Sidebar content for Dave's blog & Blogspot
• [ ] Old blog posts
• [ ] TBIY
• [x] Navigation banner (text and organization)
• [x] Pesterlog button text
• [x] Credits
  • [x] Sound
  • [x] Art
• [x] Adventure logs (w/ https://github.com/Bambosh/unofficial-homestuck-collection/pull/46)

Misc implementation:

• [x] Page.vue: footnote should give a list, not a string

• [x] Footnote support

• [x] Preface support

  • [x] Possible CW shorthand w/ styles? like hs2 did

• [ ] Data stored as lists (blog, etc) should be keyed to dates

• [x] TabFrame.vue

• [x] Remove search.json entirely, populate search from real data

Logs done with #46

For what it's worth, I checked the Internet Archive and it doesn't seem the SBaHJ page ever had any equivalent of a bunch of other comomics to! when every published comic was visible.
