cups-filters 1.28.6 released!

[Till Kamppeter <till.kamppeter@gmail.com>]

Hi,

I have released cups-filters 1.28.6 now, with the following changes:

	- libcupsfilters: In generated PPDs add a grayscale mode if
	  there are only color printing modes (from OpenPrinting
	  CUPS).
	- libcupsfilters: In generated PPDs add an "OutputBin" option
	  also if it has only one choice (OpenPrinting CUPS pull
	  request #18).
	- libcupsfilters: Generated PPDs could have an "Unknown"
	  default InputSlot (OpenPrinting CUPS issue #44).
	- cups-browsed: Removed unneeded IPP attribute additions
	  preventing the created local queues from preserving a
	  location or description the user assigns to them (Issue
	  #323).
	- cups-browsed: Removed all calls of the resolve_uri() function
	  of libcupsfilters, as these are not actually needed and in
          case the supplied DNS-SD-based URI is not resolvable, the
          function gets stuck for ~5 seconds.
	- cups-browsed: Fixed several memory leaks, mainly from the
	  code to merge printer IPP attributes for clusters (Pull
	  request #322).
	- cups-browsed: Silenced compiler warning.
	- foomatic-rip: Fix infinite loop and input from file on raw
	  printing (Pull request #318).
	- foomatic-rip: Remove temporary file created during pdf-to-ps
	  conversion (Pull request #313).

Bug fix release, fixing lots of memory leaks in cups-browsed, fixed 
cups-browsed hanging several seconds when there are local print queue 
with invalid DNS-SD-based URIs, several fixes on the PPD generator for 
IPP printers, taken from OpenPrinting's fork of CUPS, and fixing bugs on 
foomatic-rip

Please release this on Debian so that it can sync into Ubuntu.

Thanks in advance.
