Added some basic code for security check

Since Prepping API security is no laughing matter, I've went ahead and
added some basic code for a security check. It's test based and will ask
the user to answer a bunch of questions related to Python and malicious
scripting.

Am I harsh in the comments? Yes, but I think it's needed as we're
dealing with something that if done wrong could compromise user systems.
As I stated in #329

I don't care about what other addons do, our audience is full of 12 year
olds that want to have fun by making Minecraft animations, security is
certainly not on their minds.

I'll be pulling example code from Python malware I find on the internet
(to those that submit that code on GitHub for people to be aware and
comment it well, I'm grateful), so there's going to be a varity of code
in these questions.

+# Hello there, StandingPad here, it seems like you want to use 
+# the Prepping API! Well let me let you in on a little secret.
+#
+# If you do not understand Python or what Python code
+# is unsafe, or you do not verify your downloads, then 
+# DO NOT ENABLE THIS API. Seriously, this API allows arbitrary 
+# Python scripts to run in place of Prep Materials (that's the whole
+# point), and Murphy's Law states:
+# > Anything that can go wrong will go wrong.
+#
+# We are not responsible for any damage that occurs to your system by
+# this API. If damage occurs, then IT IS YOUR FAULT.
+#
+# "Can't you use do that sandboxing thing?"
+# No, we can't, not in Pure Python. The creator of Pysandbox says it himself:
+# > I now agree that putting a sandbox in CPython is the wrong design. There 
+# > are too many ways to escape the untrusted namespace using the various introspection 
+# > features of the Python language.
+#
+# If you have to Google the answers, then guess what? You should not use this API. I'm sorry
+# for being harsh, but that's the harsh reality. This API is powerful, but can seriously do damage
+# if you run a script that is malicious
+#
+# With that, if you still don't want to listen, I guess you can continue on. Don't blame us MCprep
+# developers if through your negligence you end up losing everything on your system.
