Added functionality for: reactivity selection, matchAll words, weights and user of Enter to start search

[aitorhh]

I have added some functionality to the easy:search and easysearch:components:

• Select if the query is reactive: for big queries this is important
• Use enter to start the search instead of while writting (autoSearch={0, 1})
• Indicate to the input field if the match of words uses AND or OR operator (matchAll={0, 1})
• Weights added for the MongoTextIndex (I didn't get to work with the default version)
