Few small changes:

    * Travis should build with cmake too, just as a sanity check
    * Fixes a 'missing initializer' warning.
    * Change the inproc:// endpoint for actor so it cannot conflict anymore.
    * pedantic warning in z85.hpp
    * Prevent shadowing warning when compiling with certain flags

Few code cleanup / fixes
Expose the read_cursor for zmqpp::message.

This enables to use the stream-style reader interface
with get_raw().
Merge pull request #71 from gyulalaszlo/expose-message-read-cursor

Expose the read_cursor for zmqpp::message.
Add test to zmqpp::message move constructor/assignment operator.

These tests fail.

It shows that read_cursor is not properly
updated when moving messages. It can cause trouble with
using operator>>. See #73.

Also, when using operator= the moved-from message ends up with
parts from the moved-to message. This is incorrect.
Problem: zmqpp::message move-constructor and operator= misbehave.

See previous commit for tests explaining those problems.
Merge pull request #74 from xaqq/message_move

Message move
Fix compilation issue against libzmq master.

Since libzmq master now aims toward 4.2 some issues with preprocessor #if
arised. This commit corrects those.
Add support for new ZMQ_POLLPRI flag.

I recently added a ZMQ_POLLPRI flags for polling events. This
adds the support of this flags to zmqpp.
Merge pull request #75 from xaqq/pollpri

POLLPRI support + compilation fixes
