Improve Scene Tree Dock's Node filter (Allow multiple terms & more)

Browse Source 
- Allows more than one parameter to be passed in the "Filter Node" search box, each term separated by spaces.
- Grays out any parent Node not matching the search, but still having to be there because a child is.
- Adds a `group:` filter. It matches any Node belonging to the passed group. If no argument is passed, it matches all Nodes belonging to any group. It also ignores groups used internally, and its alias is `g`.
