* added (wip) ssl net support: this has been implemented as an extension to net_tcp (or std_protocol<tcp::socket>), which now takes an additional bool template argument which determines if ssl should be used or not; note: any program/library using this has to link "crypto" and "ssl" now
 * (wip) restructuring of irc_net: no longer inherits from the net class, but instead creates/has/uses two net objects (one with ssl, one without ssl; the working part is still wip); moved all template functions into the class definition (due to insane template repetitiveness)
 * some cleanup in the net class (the net class will be changed soon to also support ssl)
 * no need to use the __FILE__ and __func__ macro when calling log_undecorated(...)
