The LexicalPath instance methods dirname(), basename(), title() and extension() will be changed to return StringView const& in a further commit. Due to this, users creating temporary LexicalPath objects just to call one of those getters will recieve a StringView const& pointing to a possible freed buffer. To avoid this, static methods for those APIs have been added, which will return a String by value to avoid those problems. All cases where temporary LexicalPath objects have been used as described above haven been changed to use the static APIs.
