modified formatting of Load Average at top

Formatting in the bash shell version was modified to allow for seeing the whole hour's loads with "head -n1".  It's hard to grep on "-->", so I changed the output from:
-----
Load Average:


20140820 11 56 --> load: 1.87 4.83 3.74 2/504 22014
-----

To: 
20140820 11 56 Load Average: 1.87 4.83 3.74 2/504 22014
