Fix the width of the machine view panel and contents.
Merge pull request #267 from huwshimi/machine-view-width

The width of the machine view panel were not correct, the columns were mis-aligned and the header was sitting under the sidebar.

QA:
Use mv flag. Deploy a service and open the machine view.
Check that the columns do not have a space on the left.
Check that the header does not display under the sidebar (there is not a visual difference, you'll need to inspect the element to see the change).
