We had a mixture of tab and 4space based indenting, which is a bad idea. 4space is the standard in python, so convert all our code to that. The result unfortuantely still shoed even more inconsistencies, so I've decided to run autopep8 on the entire code base. Change-Id: I4a4b1b444a2f43fab05fc5d2c8a7dd6ddecb5f07
