Saving and showing tags
Added the markdown lib

So app engine won't bomb out
Fixing the tags problem

Same tag is reused instead of creating separate tags for each question.
Adding a question detail page

To view individual question & answers.
Added bootstrap library

Also makes entering question easier by predefining some tags.
Attempting to fix question type data

Instead of having the question type entity, will just make use of the
tag entity. So multiple-answer, short-response will be a tag that
questions use. This fix is incomplete yet.
