percentages are returned in args_dict['ibytes']

[geekscrapy]

Once generate_graphs() is called on graph ent, 'percentages' values are appended to the ibytes list.

To replicate:

• Import and submit graph to generate_graphs(args_dict)
• print args_dict - it shouldn't contain the 'percentages' list

I believe this is due to not copying the dictionary, but using the deepcopy.
