Audiopreview

The "R" shortcut was added to restart playing the current stream. The "P" shortcut was added to play the previous stream in the queue list. "[paused]" is now shown when the stream is paused, instead of "[playing]". Capital letter equivalents are now accepted for shortcuts. A problem in which the stream title/duration were not shown when STDERR is a file was fixed. The "g_set_prgname" multiple-call warning was fixed. Lots of code clean-up was done.

Track information is now displayed in colors. The --colors option was implemented. The --loop option was added to play the stream list in a loop. A problem with putting audiopreview in the background and being stopped by SIGTTIN was fixed. Errors when the DISPLAY environment variable is undefined or empty were fixed.

This release adds support for --max-duration (useful with --entirely). It prints stream info depending on terminal column size to avoid line-wrap. Previous autogen.sh changes have been reverted. There are other minor changes/fixes.

This release adds the keyboard shortcuts "N" to play the next stream,
"Spacebar" to pause/resume playing, and "Q" to quit, better duration
checks and better tracking of the current stream, and support for simple
playlists (newline-separated lists of files). It fixes segmentation
faults with very long arguments, a few memory leaks, warnings being sent
to STDOUT instead of STDERR, a possible race condition, and a minor
packaging-related issue with potfiles.in.
