Search feature

[jetcanfly]

This is the search feature. Access it in search/. I used third-party libraries: haystack(framework), whoosh(search engine). Establish search index with question title, question content, question's answers' content. The search has been implemented vague match at the first place so you can search with non-adjacent keywords. If it's the first time you try to use search, please execute: python manage.py rebuild_index The result is shown as question title and question creation date. Future work: add a shortcut input windows in nav-bar in base.html for more convenient use of searching.

It looks confusing because what I commit are not supposed to affect existed tests.
