Bug Fixes:
#266147 : Verify signature of the encrypted text, if any. (Milan Crha)
#534938 : Remember which IDs we added to the folder and ignore these in report of recent messages, because we know about them already. (Milan Crha)
#555888 : Use proxy configurable within Evolution.
#567861 : Two sources also differ when one has set color_spec and the other not. (Milan Crha)
#569459 : Revert back to including <libical/ical*.h>. This is what is suggested by the upstream folks. Since libical.pc (in 0.43) has a problem with its CFlags, make necessary adjustments. (Suman Manjunath)
#570653 : Kill n_std_folders and use G_N_ELEMENTS (std_folders) instead. (Matthew Barnes)
#571726 : Fix a translatable string typo. Does not break string freeze. (Matthew Barnes)
#571761 : Stop using deprecated GtkType macros. (Matthew Barnes)
Other contributions:
AC_HELP_STRING instead of AS_HELP_STRING which doesn't work for me at least... And the file uses AC_HELP_STRING in all other places already anyway. (Tor Lillqvist)
Fix -Wold-style-definition warnings (Andre Klapper)
Expose the right CFLAGS for libical headers. (Suman Manjunath)
Use correct server parameter for getting folder information (Sankar P)
