As pointed out in #79, the documented command `\weblink` is actually
implemented as `\link` (see also
f3dd14ff62/moderncv.cls (L572)).
This change thus fixes the docs and reduces confusion for users who copy
this code from the documented example in the manual.
Userguide v2 was never, the old one was deleted. It is still out of date and currently doesn't even build.
