Simon Michael d4965b87ff web: -fweb now builds with simpleserver; the alternate -fwebhappstack builds with happstack
hack-handler-simpleserver is presumably quite a bit easier to install than
happstack, and so far fits hledger's needs just as well, so it is now the
default when installing with -fweb. To build with happstack, use
-fwebhappstack instead.  hledger --version shows which webserver was
built. Also webserver thread management has been simplified so should be
more consistent across platforms.

The main function is in this separate module so it can be imported by
benchmark scripts. As a side benefit, this avoids a weakness of sp, which
doesn't allow both #! and \{\-\# lines.
