alfred: bump version to 2013.4.0
bump alfred to version 2013.4.0. From the CHANGELOG:
* add new json output format for vis
* add gps location information service for alfred
* allow network interface to vanish and return without restart
* allow to switch between master and slave operation without restart
* renamed vis to batadv-vis to avoid collisions with other vis binaries
* add manpages
* various code cleanups
* bugs squashed:
* handle failing write() in unix sockets
* Fix crash when vis opened empty file
alfred-gpsd is optional and requires libgps from the gpsd package to
compile. It needed its own -lm for libgps which does not link to libm
by itself, a patch for upstream alfred has been posted.
