Renamed zbeacon_pipe to zbeacon_socket
- left old method for compatibility, but marked as deprecated
- 'pipe' was too specific about internal use of this socket
- want to make this consistent with zsecure_socket ()
Selftest tags were wrong
Removed zcurve class
- no real use cases for CZMQ applications
- moving to clab experimental/incubator project

zcurve needs more layers to be useful; e.g. a socket wrapper that lets you
send and receive clear text messages, authentication plugins, etc. I want to
make these but don't want to pollute CZMQ. The obvious use cases aren't
compelling yet. I'd rather use ZMTP 3.0 for FileMQ and Zyre, for instance.
So I'm starting libclab, which is a C Laboratory for experimental classes
that might get into CZMQ if they prove useful.
Version number is now updated in include/czmq.h only
Version number should be 1.4.2
Updated platform builds to cover all classes
Removing demo directory
- these examples appear to be dead
- code style is not consistent with CZMQ style standards (CLASS)
- we have more complete demos elsewhere (FileMQ, Zyre at least)
Removed old unused build file
Working on issue #187
Merge pull request #188 from hintjens/master

Removing zcurve from CZMQ
