Changes since 1.3:	+253 -283 lines
Log Message:	- changed name - updated the example config to the new system - added more documentation - enhanced documentation generators - added a link to the pdf to the website - added an RSS feed generator - transitioned hooks to c++ callbacks - did various merges with upstream along the way - added const where appropriate - removed the old block allocator - fixed most memory leaks - transitioned some dictionaries to std::map - transitioned some lists to std::vector - made some free functions members where appropriate - renamed string to dynstr and added a static string ststr - use NOW instead of time (NULL) if possible - completely reworked database backends, crypto handlers and protocol handlers to use an object factory - removed the old module system. ermyth does not do any dynamic loading anymore - fixed most of the build system - reworked how protocol commands work
