Seal doesn't allow you to search multiple word queries with urlformats

[kevinforrestconnors]

To fix this, change the function choicesURLPart to replace spaces with +, which should work for most search systems. At the very least, it won't break the program like the current behavior

    function obj.choicesURLPart(query)
        --print("choicesURLPart for: "..query)
++
++      query = query:gsub(" ", "+")
++
        local choices = {}
        for name,data in pairs(obj.providers) do
            local data_url = data["url"]:gsub("([^%%])%%([^s])", "%1%%%%%2")
            local full_url = string.format(data_url, query)
            local url_scheme = string.sub(full_url, 1, string.find(full_url, "://") - 1)
            local choice = {}
            choice["text"] = data["name"]
            choice["subText"] = full_url
            choice["plugin"] = obj.__name
            choice["type"] = "launch"
            choice["url"] = full_url
            choice["scheme"] = url_scheme
            table.insert(choices, choice)
        end
        return choices
    end
