Simple Implementation In Stroybook Of SearchInput

By the way, I added *~ to .gitignore, which are the backups of emacs editor.
See the Storybook of SearchInput.
Problems:
* I found no way to separate the heading of the search results from the first item. Do we have to write a complete new component for this?
* The incoming data must by sorted by type before passed to the component. I added keys searchType and firstType, to identify the type (post/user) (may be as a locale) and to know when I have to place the heading.
