Layouts block: Extend search functionality to work with name

[mindctrl]

The layout modal searches the keywords field. An internal tester expressed confusion that searching for a word in the layout's name didn't show layouts matching that term. In this case all the words in the layout's name were not included as keywords, therefore no matches.

Describe the solution you'd like
Extend the search functionality to also check the name field. The layout's name is the only way users can refer to the layout, as keywords are hidden.
