As @ametaireau suggested: instead of having logic that prepends the
OUTPUT_SOURCES_EXTENSION with a '.' we allow the user more
flexibility to control the extension that can be used.
Using this configurable setting users can control what extension will be
appended to filenames by the SourcesGenerator.
The default is to use the ``.text`` extension.

Since PyPI doesn't seem to handle anything but the most basic of reST
formatting, moving the inline links to the end of the file should
improve readability when the file is viewed in its raw form. Also
updated changelog with the 3.0 release date.
Restore "make serve" to a non-backgrounded SimpleHTTPServer process and
give the develop_server.sh its own make target at "make devserver".
Add a few missing make targets to the help list and re-order targets for
consistency. Add note to docs regarding how to stop the devserver.
Some folks have run into trouble when configuring settings because
they wrap integer values in quotes or forget quotes for string-based
values. Added clarification to docs that will hopefully reduce confusion
in the future.
Then we bypass all feed generation of both are set to None or throw a warning if SITEURL is unset.
Updated all documentation, to make sure the usage and warning is clear.
