Subject: content: rename articles to reinforce convention of short URLs

The Go blog started out on Blogger
(http://web.archive.org/web/20100325005843/http://blog.golang.org/).
Later, we moved to the current self-hosted blog server
with extra Go-specific functionality like playground snippets.

The old Blogger posts have very long URLs that Blogger chose
for us, such as "go-programming-language-turns-two" or
"two-go-talks-lexical-scanning-in-go-and", predating
the convention of giving posts shorter, more share-friendly,
typeable names.

The conversion of the old Blogger posts also predated
the convention of putting supporting files in a subdirectory.

The result is that although we've established new conventions,
you wouldn't know by listing the directory - the old Blogger
content presents a conflicting picture.

This commit renames the posts with very long names
to have shorter, more share-friendly names, and it moves
all supporting files to subdirectories. It also adds a README
documenting the conventions.

For example, blog.golang.org/go-programming-language-turns-two
is now blog.golang.org/2years, matching our more recent birthday
post URLs, and its supporting files are moved to the new 2years/ directory.

The old URLs redirect to the new ones.
