Update the documentation on getting started with development.
Review Request #7630 — Created Sept. 15, 2015 and submitted — Latest diff uploaded
This updates the documentation to modernize some of the steps, such as using pip instead of easy_install, and using RBTools and devserver.py correctly. The biggest update has to do with the list of dependencies, which no longer includes the Python modules that will be automatically installed by prepare-dev.py. There are also a variety of other small updates for URLs and branch names.
Built the docs and looked through them.
