eM Client

What's new in this version:

Changes:
cli:
- Added a new flag (--trace-uncaught) that makes Node.js print the stack trace at the time of throwing uncaught exceptions, rather than at the creation of the Error object, if there is any. This is disabled by default because it affects GC behavior

crypto:
- Added Hash.prototype.copy() method. It returns a new Hash object with its internal state cloned from the original one

dgram:
- Added source-specific multicast support. This adds methods to Datagram sockets to support RFC 4607 for IPv4 and IPv6

fs:
- Added a bufferSize option to fs.opendir(). It allows to control the number of entries that are buffered internally when reading from the directory

meta:
- Added Chengzhong Wu to collaborators
