WIP: Fork wiki

[chrisekelley]

fork dat feature is implemented; however, when you access the forked dat in the bunsen-ui iframe, you get the following error:

random-access-idb@latest.js:998 Uncaught (in promise) DOMException: 
Failed to execute 'open' on 'IDBFactory': 
access to the Indexed Database API is denied in this context.

Here is the source for the forked wiki: https://github.com/chrisekelley/dat-wysiwywiki-app

Thinking about this issue - maybe it makes sense for the wiki to fork itself? I am assuming this is a sandbox issue. Pondering:

• Does an iframe-in-another-iframe not have any indexdb access?
• Or is the issue that a dat is trying to manipulate its own structure?
• Maybe whenever the wiki needs to be updated. it must fork itself and make changes to its fork.

Note the change to the release script - it first assumes that you have already copied the .dat file to the root of your repo so that it doesn't get clobbered each time you build.

You may want to add code here to double check that DatArchive.DefaultManager exists before trying to set the manager. (for when the code is loaded in beaker)

Oh dang, it seems IndexedDB just doesn't work in iframes. :(

Luckily, I've basically finished my work on dat-polyfill which stores data in the parent frame's indexedb and as such de-duplicates all dats between origins. (Also provides support for DatArchive.selectArchive through hooks in the parent)

Check out the demo code

Did you add all the sandbox parameters to the iframe that's contianing bunsen-ui?

@RangerMauve thanks for the tip - Still working on this - the past week I created a vanilla js version of the shell - Angular was a bit overkill for what we need here.

Nice! Always a good feeling to delete a bunch of code. :D
