Changes & fixes
- The builtin search will now default to skim-v2 based fuzzy matching.
- esc while in search mode will recover the initial focus (i.e. cancel the
  search).
- The following messages will be available for search based operations:
     SearchFuzzy
     SearchFuzzyFromInput
     AcceptSearch
     CancelSearch
- Quick scrolling operations are supported using the following messages and keys:
     ScrollUp page-up

     ScrollDownHalf }

Note: People who prefer the old regex based search, can use the
regex-search.xplr plugin.
