v1

This is the first release of tlog. It is not ready for production and
should be considered a development preview.

Features implemented so far include:

• Recording of user input, program output and window size changes.
• Support for writing into syslog and files.
• Tlog-rec configuration through system-wide configuration file
  /etc/tlog/tlog-rec.conf, environment variables and command line.
• Very basic playback directly from ElasticSearch.
