Get rid of all this environment variable bullhooey

[eddieantonio]

Having to export all these environment variables is darn irksome:

export ESTIMATENGRAM
export TEST_FILE_LIST
export LD_LIBRARY_PATH
export VIRTUALENV_ACTIVATE
# WHYYYYYYYYYYY?

---

• ESTIMATENGRAM should be obsolete soon, see UnnaturalGrams Python Extension Module #12
• LD_LIBRARY_PATH same as above
• TEST_FILE_LIST is.. not actually needed anymore, since it can just rely on the test corpus (Test Corpus #6)
• VIRTUALENV_ACTIVATE This is misleading. It's the virtualenv of the project we're siccing unnaturalcode at... I think. I'm not sure if this is strictly necessary, if the virtualenv of the project is already activated. It might be possible to determine this automatically (see Automatically create and activate the virtualenv of the test corpus #14)

• there has to be a better way

If MITLM is installed globally you don't need half of the environment variables, TEST_FILE_LIST is fixed, VIRTUALENV_ACTIVATE could be fixed by Eddie since he seems to have some idea.
