fix build with recent zeromq
bring in the changes from process isolate
Major cleanup.

Chrono and filesystem plugins are moved into the core, as they do not
depend on anything except it, so there's no point in keeping them
separate.

Perl plugin is removed, it was abandoned long ago, and now we don't need
language support plugins at all.

Added .install debhelper files for blastbeat and urlfetch so that these
plugins are actually installed. These plugins are not used in production
yet, so it wasn't critical that their packages were empty previously.
Merge branch 'master' of github.com:cocaine/cocaine-plugins
Bring in changes from the process isolate.

Adapt current working directory path from the process isolate, as well
as use the quick exit path on post-fork failures.
Enable URLFetch service packaging.

The one and only nuclear-powered coder Ruslan Nigmatullin finally
managed to packetize his Swarm library, so we can enable building of
the URLFetch packages.
Copyright header bump.

It's year 2013 already, time to bump our useless copyright headers. Also
fixed a typo in Ruslan's last name.
Proper order of eventloop initialization.

For some reason, eventloop watcher structures initialization was
postponed even though there was no reason to do so, as these watchers
only depend on the eventloop itself.
Proper build dependency detection and linkage.

URLFetch should only search for it's dependencies when the plugin is
enabled. Dealer should use detected include and library directories.
CGroups and Blastbeat plugins were missing some of their link libraries.
Release 0.10.2.

Mostly bugfixes and minor improvements. Consult debian/changelog for
release details.
