[boost] informal boost summer of code IRC channel invitation

Hello, We have created an informal boost-soc channel on irc.oftc.net. As we're entering the final month of the summer of code program, this might be a good place this years participants, last year's participants, mentors, and those interested in the project, to hang out, answer quick questions, provide moral support and negotiate stress-relieving (hopefully) online chess matches. The channel name is boost-soc. Everyone is invited! Stjepan
