Kyua Testers 0.2: New TAP tester

Changes in version 0.2

Experimental version released on December 7th, 2013.

• Issue 74: Added the kyua-tap-tester, a new backend to interact with
  test programs that comply with the Test Anything Protocol.
• Issue 69: Cope with the lack of AM_PROG_AR in configure.ac, which
  first appeared in Automake 1.11.2. Fixes a problem in Ubuntu 10.04
  LTS, which appears stuck in 1.11.1.
• Issue 24: Improve test case isolation by confining the tests to their
  own session instead of just to their own process group.
