Help search also inside description column

[yanshay]

I'm new to joshuto so use the Help view. Currently when searching in the help using '/' it searches only the key and command columns. I actually need the search to search in the 'Description' column. So I modified the search code to search also in the Description column and do a case insensitive search.

Can you run cargo fmt? Thanks!
