Optimization potential in LanguageFilter::Init

[xezon]

void LanguageFilter::Init()
{
    m_wordList.clear();

    File *file = g_theFileSystem->Open_File("langdata.dat", File::READ | File::BINARY);

    if (file != nullptr) {
        unichar_t buf[128];

        while (Read_Word(file, buf)) {
            int len = u_strlen(buf); // Get rid of this

            if (len != 0) {
                for (int i = 0; i < len; i++) {
                    buf[i] ^= 0x5555;
                }

                Utf16String str(buf);
                Un_Haxor(str);
                m_wordList[str] = true;
            }
        }

        file->Close();
    }
}

We can get rid of int len = u_strlen(buf) by having Read_Word return the word count and then use that as len instead.
