luci-base: add support for DynamicList with FileBrowser

Two new arguments url, defpath were added to cbi_dynlist_init() for
initializing the brower button.

An example of usage

    identity = section:taboption("general", DynamicList, "identity",
	    translate("List of SSH key files for auth"))
    identity.datatype = "file"
