gEDA-dev: [PATCH] Allow gschemdoc to access wiki pages with -w.

[Peter TB Brett]

Adds the gschemdoc -w switch to make gschemdoc load a wiki page.
It initially tries to find a local export of the wiki; on failure,
it falls back to the online wiki at the gEDA website.

See also SF.net Patch #1702302.
