[Haizea] Problems with Haizea and OpenNEbula

Is the ONE_AUTH environment variable set up? This variable is described 
in the OpenNebula documentation 
(http://www.opennebula.org/doku.php?id=documentation:rel1.4:cg). 
Basically, you need to export an ONE_AUTH variable with the username and 
password of the OpenNebula admin user:

	export ONE_AUTH="oneadmin:foobar"

The OpenNebula 1.4 API now requires that a password be sent with each 
request and, for consistency with OpenNebula, Haizea takes this password 
from the same location OpenNebula does (the ONE_AUTH environment variable)

However, I just realized that the Haizea documentation doesn't refer to 
this; I will make sure to change this in the next release (a new beta is 
coming out tomorrow). I'll also make sure that Haizea prints out a more 
informative error message when it doesn't find the ONE_AUTH variable.

Cheers!
