Change notifications support for Bibles with dots in their name

[teusbenschop]

Currently if there's a Bible with a dot "." in its name, and there are change notifications for that, these don't get generated.

    std::vector <std::string> bits = filter::strings::explode (file, '.');
    if (bits.size() != 3) continue;

Additionally if the name starts with a ', it won't work either.

See the attached file for examples of that.
