Bump version for new release.

Alter ETA calculation to use the rate over the past 30 seconds instead of over the whole transfer, and allow that 30 second window to be adjusted.

-Introduction
-************
-
-This is the README for `pv' ("Pipe Viewer"), a terminal-based tool for
-monitoring the progress of data through a pipeline.  It can be inserted into
-any normal pipeline between two processes to give a visual indication of how
-quickly data is passing through, how long it has taken, how near to
-completion it is, and an estimate of how long it will be until completion.
-
-
-Documentation
-*************
-
-A manual page is included in this distribution.  See `man ./doc/quickref.1',
-or `man pv' after installation.
-
-
-Compilation
-***********
-
-If this is not a packaged release, first run "./generate.sh".
-
-To compile the package, type "sh ./configure", which should generate a
-Makefile for your system.  You may then type "make" to build everything.
-Note that GNU `make' is required; this may be installed as `gmake' on some
-systems, so if typing "make" gives an error, try "gmake" instead.
-
-See the file `doc/INSTALL' for more about the `configure' script.
-
-Developers note that you can do "./configure --enable-debugging" to cause
-debugging support to be built in, and "--enable-profiling" builds in
-profiling support (see "man gprof").  Also note that doing "make index" will
-generate an HTML code index (using "ctags" and "cproto"); this index lists
-all files used, all functions defined, and all TODOs marked in the code.
