Added alias cr for cmus-remote.
New feature match_sequence.

* With match_sequence you can easily detect a sequence of log lines that match
  certain patterns. Without this extension one can only work on the data of the
  current log line.
* Default setting for repetition detection is now disabled because it may
  confuse new users.
Added contols for Pulse Audio.

With this release the Pulse Audio sink's volume and mute status can be
remote-controlled, too.
Number of output lines can be set by parameter.

The default remains one line of output.
Write events to stdout.

This allows tracking (logging) of the points in time when the screen
has been (un)locked.
Additional shortcut for a shiftwidth of 3 columns.

Usually I do not like odd numbers for indentation,
but this is common for bullet lists in twiki et al.
Added pager env variable with value less.

Also, set an env variable to have less search case-insensitively by default.
