Release pgloader 3.5.1.

Lots of bug fixes did happen, time to release.

Release pgloader 3.4.1

Prepare release 3.3.2.

Add tzdata to build-depends (Closes: #839468)

Release pgloader v3.3.1.

Add a bundle distribution.

Using Quicklisp bundle facility it is possible to prepare a
self-contained archive of all the code needed to build pgloader.

Doing that should allow users to easily build pgloader when they are
being a restrictive proxy, and packagers to work from a source tarball
that has a very limited build dependencies.

Merge branch 'master' into rel_3_2_stable

And upgrade version numbers straight to 3.2.2 rather than "just"
resolving the conflicts.

Fix Makefile and bash multi-line escaping...

Travis is unhappy about the spelling of the command, so let's not try to
be cleverer here and accept a runaway line here. See dimitri#153 too.

Prepare for release 3.2.0.

Update web/download with the new release.
