Aegir 0.4 alpha 2 released

The Aegir team is happy to present the second alpha release of the 0.4 milestone. Like the first alpha, this is a "developer preview" release following the hugely popular 0.3 release, which includes many bug fixes to alpha1, along with a stack of exciting new features. While we are in alpha stage with 0.4, we recommend that production system continue to use the 0.3 stable release for now. However, many important bug fixes did make it into this alpha, so we encourage you to check it out however way you can.
