Javascript resources should be presented to browsers after CSS, and
"after the fold" (ATF) according to the best practices:
https://developers.google.com/speed/docs/insights/mobile#PutStylesBeforeScripts
This change allows the browser to download Javascript files in
parallel, by including Javascript on the *closing* </body> tag instead
of the opening tag.
We also improve the regex to tolerate spaces before the body tag, as
some templates have (proper) indentation for the tag.
Add an inject function, that can be used by plugins that want to replace
one of ikiwiki's functions with their own version. (This is a scary thing
that grubs through the symbol table, and replaces all exported occurances
of a function with the injected version.)
external: RPC functions can be injected to replace exported functions.
Removed the stupid displaytime hook, and use injection instead.
Need to use a hook because an exported function cannot be reliably
overridden. The replacement verstion was actually only affecting plugins
loaded after it.
formattime doesn't need a hook, since there's no reason to export it.
