The idea is that you regenerate the man pages in the same commit you
alter them: that's how we know whether to try regenerating them or not
(git doesn't store timestamps, so it can't really tell).
Travis will now check this, so force them all to sync to this commit.

Fixes: #3192
Changelog-Added: `waitanyinvoice` now supports a `timeout` parameter, which when set will cause the command to fail when the timeout is reached; can set this to 0 to fail immediately if no new invoice has been paid yet.
mrkd started enforcing the `name -- short description` style of top-level
headings somewhere, and was thus failing to build the man-pages. I swapped
the title and with the existing short description to make it work
again. `mrkd` will automatically infer the section from the filename so no
need to put it in the title as well.
In addition I removed the "last updated" lines at the bottom since they are
out of date at best, and misleading at the worst. If we want to keep them, I'd
suggest generating them from the commit that last touched them.
