Added Search

Added a search feature.  I don’t think I’ll use it much but I figured I may need it one day and I was at a lull. 

It’s pretty basic you can search the posts title or body.  What makes it a little bit cool is that I can search for a specific tag and there is a check box to only return posts marked as favorites.

Eventually I’ll add an advanced search so I search by feed or date range among other standards search options.
