Gadu-Gadu protocol update and patch

[Tomasz Sałaciński]

Hello,

There are the four patches to Gadu-Gadu protocol in Pidgin - libgadu
update to 1.8.2 (this fixes a few security issues, for more info email
me):

http://www.alarm-clock.pl/libgadu_1.8.2.patch
http://www.alarm-clock.pl/Makefile.am.patch

These patches fix the following issues:

- Formatting broken when occurs after image in the message
- Show correct date when receiving images
- Allow sending of images with correct formatting

http://www.alarm-clock.pl/gg_images_gg.c.patch
http://www.alarm-clock.pl/gg_images_gg.h.patch

I've used GPtrArray to store positions and values for formatting, and
GKeyFile (stored internally) for crc->purple image id information.

If you have any suggestions, feel free to tell me.

Regards,
Tomasz Sałaciński
