Search by category name

[IlyaSmagin]

I think it would be nice if I could be searching by category name, especially when starting on expanded view

Here is an example for searching effects category:

initial view

eff search

The only possible problem is that after accepting this change some search results will change, 'cause more results will be visible, here is example for spacing search query:

old

new

I believe this will greatly improve user experience and I've already implemented this change in my #32 PR
Any feedback is appreciated!
