Title: Add a common base class for string handlers

Added an abstract class ```TagLib::StringHandler``` as the common base class of ```TagLib::ID3v1::StringHandler```, ```TagLib::ID3v2::Latin1StringHandler``` and ```TagLib::RIFF::Info::StringHandler```.
This patch aims to allow users not to implement duplicate string handlers.
