More generous search

[d-buchmann]

Split the keyword into tokens (at spaces).
Search for every token individually, then combine results with AND.
Caution: This has no effect on the typeahead search, I will have a look at this soon.
Should fix #892.

I wonder if it might be better to use the fulltext seach capabilities of the database then trying to implement more complex searches ourselves.

[virtadpt]

@jbtronics Generally speaking, that's always a good idea. Let the database server do the heavy lifting.

[d-buchmann]

The feature is plain simple. I just make the query more complex by splitting the search string.
So, the database server is still doing the heavy lifting, even though it's not making use of additional database features (which I didn't know of before :)
I did my research and see that native full-text search would definitely be the better solution, but as I see it, it would require quite a bit of work, because all databases have different syntax, feature sets and restrictions. Doctrine also doesn't seem to have this built-in - please correct me if I'm wrong.
