Do not use queryfilter on "play next" and "add to up next" commands
Merge pull request #29 from chme/retune

Improve support for "play next" and "add to up next" with Retune
Honor the "ek" (encryption) flag for RAOP_DEV_OTHER + slight rewrite of raop_device_cb
Additional quick install info
Extra error check
Some filesystems have mtime=0 (Seafile), so add check for stamp before
letting the scanner exit with just a db ping
Modify configure script:
- make check for libavresample dependent on libavcodec (since the resample functions were removed from libavcodec)
- check for libevent 1 or >=2.1.4 but don't bail if other libevent is also present
Modifications to the playqueue-clear command:
- do not stop playback when clearing the UpNext queue
- clear history, if mode=0x68697374 ("hist")

Merge pull request #32 from chme/doc

Added comments to queue_clear and queue_empty
ICY scanner modifications
Migrate all evhttp to non-deprecated libevent2
- well except a troublemaker in httpd_daap.c (req->flags &= ~EVHTTP_PROXY_REQUEST)
Make compatible with libevent 2.0 by crippling streaming and ICY metadata (see issue #30)
Setting log level to info gave a lot of meaningless db.c messages
Libav 10 (and ffmpeg) now has native support for ICY metadata
Change log level of .remote message to ease pairing troubleshooting
INSTALL update to reflect compability with libevent 2.0
Fixup new libav 10 icy extraction
