Added indentation to JSON
Deleted old or obsolete server files

Some will be replaced by newer versions.
Added potentially useful image files

From original ToonTalk. Will experiment with integrating them.
First incomplete draft of birds and nests
Using array push

Instead of arr[arr.length] = x

for clarity and abstraction that may be replaced with something else
someday.
Introduced 'match' utility function

This way all matches handle nests properly without special code.
Added support for relative and absolute img sources

If relative path doesn't work uses the absolute path to GitHub.
Added nests to index HTML files
Robots, birds, and nest images use utility function

So they can fall back on absolute URL when necessary.
