Ignore jekyll's _site directory
Plug Algolia's Search API (auto-complete + instant-search)
 - What's new ?
   - typeahead.js-based search input (auto-completion)
   - highlighting
   - typo-tolerance (both in instant-search and auto-completion)
 - Push datas to Algolia's indexing server ?
   - ```grunt``` generates ```batch.json``` from ```bath.handlebars```
   - ```grunt index-icons --apikey PERSONAL_API_KEY``` pushes ```batch.json```
 - Enjoy it !
Removed typeahead.js-based auto-complete (quite useless).
Restore responsive .entry-related classes.
Keep the alphabetical order when the query is empty.
Sort by name by default, no need to sort using JS.
Prefix query on all words.
