request for support of "single" mode and older versions of MPD

[kwhite-uottawa]

I'm been looking into trying ymuse as a replacement for cantata. I have two main MPD servers: one stuck at (patched) 0.17.0 due to its better handling of embedded cuesheets; and one a more recent (unpatched 0.23.5) version for testing newer embedded cuesheet support. (Most of my music is in flac files with embedded cuesheets.) My listening habits are typically "consume" always on, set "single" when I want to have a break when the current track completes.

What I miss using ymuse connected to the old MPD 0.17.0 version:

• support for "single" mode (not tied to repeat)
• support for old style search
• support for track lengths

What I miss when connecting to the newer MPD 0.23.5 version.

• support for "single" mode
• adding a file with embedded cuesheet

Attached is a POC patch that provides support for the above.

• "single" mode is done by adding another state to the "repeat" button. I'm sure a better way exists!
• When adding a file to the queue, "load" is tried before "add" just in case the file contains an embedded cuesheet
• replacement mpd 0.17 commands are used if a command fails.
