Changes since 1.5:	+2 -2 lines
Log Message:	- changed configurations to the c++ stdlib - more #defines to enum - removed getopt.h and link.h from the system as they were unused - reworked logstreams - added an itoa with old syntax - made klines objects - moved some global variables into appropriate classes - fixed boost.foreach's compiler workaround #if's - allow other files to add exceptions with ADD_EXCEPTION - changed mynick_t to c++ object - moved servers.h out of atheme.h - corrected PING from inspircd 1.2
