Duplicate dependencies/Dependency management problems

[Gabriel Hurley]

Re-installing, updating, or otherwise altering your environment could be significantly sped up by activating the built-in download caching in pip and buildout.

Moreover, Glance is installed as a dependency twice: once from pip and once from buildout, currently yielding different versions and attempting to install all its dependencies twice. The launchpad version should be removed and the version should be locked to the latest stable release.

    Download caching, dependency cleanup, run_tests improvements.

    Fixed bug 888813 -- removed duplicate installations of glance as
    a dependency in buildout. Set a required version for pycrypto
    as a dependency since older versions will fail, but 2.4 can't be
    installed by buildout. Turned on download caching for pip and
    buildout in run_tests.sh. Turned on mirroring for pip, just
    in case.

    Made the output from run_tests.sh commands a little more helpful.
    Made sure that commands like --pep8 and --pylint don't stop
    partway through due to bad exit codes.
