LMS startup optimization: lazy load pynliner

Cleaner grades exception handling

pynliner imports cssutils, which has an expensive initialization. All
told, it can account for 15-20% of "fast" LMS startup (without asset
compilation). So we're going to load it locally here so that we delay
that one-time hit until we actually do the (rare) operation that is
sending a credit notification email.

Change edx-django-release-util version.

We use the dealer.git library to determine the current revision of
edx-platform at startup time and store that as EDX_PLATFORM_REVISION in
our settings. This can take a surprisingly long time and involve a lot
of disk IO to initialize.

Studio still needs this functionality because it determines its static
asset folder based partly on the hash. This is horrible, because it
means all static assets are invalidated on every release instead of
just the ones that change. But that will be the subject of a different
PR.

Find the courses a user has certs for up front.

Before this commit, we had to do a separate query for every course a
user was enrolled in when determining whether a course was refundable
(if you have a certificate, it isn't). Now the student dashboard will
make a one-time query to grab all of a user's cert-issued courses. This
is indexed, so it should be much faster than grabbing each one
separately.
