2015-03-23 io.js v1.6.2 Release

Notable Changes:

* Windows: The ongoing work in improving the state of Windows support
  has resulted in full test suite passes once again. As noted in the
  release notes for v1.4.2, CI system and configuration problems
  prevented it from properly reporting problems with the Windows
  tests, the problems with the CI and the codebase appear to have been
  fully resolved.
* FreeBSD: A kernel bug impacting io.js/Node.js was discovered and a
  patch has been introduced to prevent it causing problems for io.js
  (Fedor Indutny) #1218.
* module: you can now require('.') instead of having to require('./'),
  this is considered a bugfix (Michaël Zasso) #1185.
* v8: updated to 4.1.0.25 including patches for --max_old_space_size
  values above 4096 and Solaris support, both of which are already
  included in io.js.
