Although WA supports automatic updating during parsing of a serialized
`kernel_config` from devlib, if the installed versions of WA and devlib
have become out of sync where WA has "updated" the old implementation it
will not attempt to update it again when devlib is later updated to use
the new implementation and therefore will not trigger the existing
checks that are in place.
Update the documentation and build system for producing documentation for
WA3 with support for automatic building on readthedocs.
Note: This is currently a WIP.
