help: add web commands to help documentation

The capabilities and URL endpoints of the hgweb server can currently
only be inferred by looking at links in `hg serve` output or by reading
the source code. I've frequently found myself wanting to quickly see
what URLs and capabilities are available.

This patch teaches the help system how to display information about
web commands and their URLs. Using a mechanism similar to revsets,
templates, etc, we can now iterate over the docstrings of registered
web command functions and display them in the help output.

Unfortunately, web commands don't currently have docstrings, so the
output is currently empty. This will be addressed in the following
patches. I apologize for the patch bomb.
