Extract URLs from SWFs

[PressStartandSelect]

When ArchiveBot hits a .swf file, it should decompile it and search for URLs in the ActionScript. This may be tricky to implement, but it would fix most problems that come with archiving Flash-based sites.

An umbrella issue for the actual crawling implementation is at chfoo/wpull#74. This issue should cover adding a future Wpull option to the arguments.

Should this be closed, seeing as Flash was discontinued ages ago, or are people still archiving Flash websites?

It was only discontinued at the end of 2020. I'm sure there will still be Flash websites for another decade because people are stubborn. And as long as such sites exist, we'll be archiving them.

[TheTechRobo]

That makes sense.
