More documentation language polishment, added trivia section.

Replaced "You can" etc with more formal stuff. IRC-Galleria "advertisement"
has now a Trivia section at the very bottom of the document. I also added
link to the mailing list at google groups. Removed [email protected].

 Igbinary is a drop in replacement for the standard php serializer. Instead of
 time and space consuming textual representation, igbinary stores php data
 structures in a compact binary form. Savings are significant when using
-memcached or similar memory based storages for serialized data. You can
-expect about 50% reduction in storage requirement and speed is at least on par

+its header file to ext/igbinary/igbinary.h. There are just two straighforward
 functions: igbinary_serialize and igbinary_unserialize. Look at igbinary.h for
 prototypes and usage.
 
 Add PHP_ADD_EXTENSION_DEP(yourextension, igbinary) to your config.m4 in case
 someone wants to compile both of them statically into php.
