[ciorceri]

In this pull request contains 2 changes

1. 'ezmoni status' has one extra parameter named '--extra' which will print multiple VM details.
   2 added a new '--parserFriendly' parameter for 'ezmomi status'.

Some comments related with those changes:

• I've tried to use the same code style in my changes, if I've failed to do that, please give me some feedback and I will try to fix that. you will see that I've used 'sys.stdout.write' instead of 'print'. The reason is this: http://stackoverflow.com/questions/255147/how-do-i-keep-python-print-from-adding-newlines-or-spaces . For python2 I don't see a simpler way to do that without to confuse others.
• I've changed the 'tabulate' name to 'print_as_table' since I've added another way to deliver the output 'print_as_lines'.

All those changes were done based on my actual needs. I hope that they help the community.

I hope this one will pass PEP8 checks.
