Save time by installing all the packages at the same time

using pip install -r requirements.txt is more efficient than doing all
the packages individually
Make the file paths more friendly to doing local development
A more comprehensive install guide, albeit specific to Suse linux?

i'm assuming 'zypper' is equivalent to 'yum' and 'apt-get'?

Make caching in get_common_page_data optional

* Adds use_cache parameter (defaults to true) to get_common_page_data.
* Uses use_cache=False from inside manage_nav_menu to force a cache miss
  and guarantee admin sees recent changes. Incidentally also means that
  student view of course_info_pages gets pre-cached on the app node the
  admin happens to be working with.
  (closes #2098)
