First commit of quuxplusone.github.com/Advent/

If I'm doing this right, this "gh-pages" branch should allow you
to play Adventure right in your browser from a GitHub URL, rather
than needing to download the .z8 file or the whole repository.

This branch will probably end up out-of-date as I make changes
to the parchment/ subdirectory of the "master" branch and forget
to merge them here manually, but if this works, it'll be pretty
cool anyway.
Bring into line with master commit 8e9d2cce.
Bring into line with master commit b900237b.

The dwarves move around properly now.
Bring into line with master commit 10067a92.

Now the dwarves won't insta-kill you with their ninja skills,
and the Ming vase will behave properly when dropped.
Add a card for my Kickstarter project. Cross-promotion, hooray!

Since http://quuxplusone.github.com/Advent/ might be getting some hits
at this point, I should take the opportunity to advertise my board game.
TODO: remove the card on May 19th.
Bring into line with master commit c0b05599.

Dwarves no longer have ninja dodging skills, either.
Bring into line with master commit 89f53a8b.

Throwing the axe at the bear now works properly.
Also, I've made the HTML pages more consistent; now they both
contain the name of the game, its authors, and a link to the
GitHub project page. The .z8 download link is pretty pointless,
but removing it feels a little bare, so I'm keeping it.
Bring into line with master commit c2820130.

Fixed a glitch with FILL VASE.
Also, added a version number to the initial help message,
so I can tell whether I'm playing the right version online
or if it's getting cached somewhere along the line.
Add a nifty slide-out effect on the Kickstarter card.

This isn't just nifty; it also keeps the card from hiding all the
sidebar links when you're on a small screen! Apologies in advance
to IE users.
Bring into line with master commit ca767de1.

Fixed a bunch of endgame bugs.

I don't know of any remaining bugs in this version of "Adventure".
Bug reports are eagerly awaited!
Bring into line with master commit 6d024cd8.

This revision fixes an infinite loop caused by a dwarf
blocking your return from a FORCED location.
Bring into line with master commit 0acd89a8.

This fixes a bug with DROP CAGE in the endgame.
Bring into line with master commit 839acbe1; remove Kickstarter ad.

My Kickstarter campaign for "Colossal Cave: The Board Game" closed
successfully on 2012-05-19, having raised $14,815!

This revision also changes the wording of the axe-throwing dwarf
message back to Crowther's original grammar.
Add the ability to play Adventure 550 online.

I still need to write the blurb for index-550.html, and eventually
provide a link from index.html (or a spiffy Javascript/CSS transition)
so that people can discover play-550.html. For now, the game is still
very buggy, so I don't mind that this is unpolished.

Bring into line with master commit b7ba6be2.
Bring into line with master commit 56957389.

Also, add a blurb about Adventure 550 to index-550.html.
Bring into line with master commit fe52b1b5.
Bring into line with master commit 9747aa20.
Bring into line with master commit e381a55e.
Update the Parchment library.

The version of Parchment (and ZVM) now in this repository
corresponds to https://github.com/curiousdannii/parchment,
revision 22b510bc.

The only change I've noticed is that @save no longer prints
a helpful message by default; I'm going to have to add the message
back into Adventure's attempt_save() routine.
