WARNING: This is a unstable release, it is actually 0.24 Beta 2 release, it 
should work like any release from the 0.22 branch, but do not blame us if it 
turns your spoon into a knive.

Changes against 0.23.1:
core:
 * SplashOutputDev: Speed-up some tiling on a 10x factor
 * Improve caching of lcms2 ICC color profiles
 * Put some private classes in an anonymous namespace

qt4:
 * Add a thread stresser tool

build system:
 * Fix mingw build

Release schedule is
 * Jun 24 - Poppler 0.23.3 (0.24 Beta 3)
 * Jul  8 - Poppler 0.23.4 (0.24 RC) 
 * Jul 22 - Poppler 0.24.0
We accept features until Beta 3

Things I have on my todo (may or may not happen)
 * Support for the NoRotate annotation flag
 * Tagged-PDF support for poppler and poppler-glib
 * https://bugs.freedesktop.org/show_bug.cgi?id=63963
 * Arthur Backend patch

Anyone helping with the review?	

Testing, patches and bug reports welcome.
