Added all gallery related files to the mythfrontend. This includes files
that handle the navigation, thumbnail generation, settings, interaction with
the database and the actual display of the image or a slideshow.

Look for gallery* and image* source files.

Like Mythvideo you need to scan on changes and images are saved in the db.
The directories are persisted in gallery_directories table.

            "CREATE TABLE IF NOT EXISTS gallery_directories ("
            "  dir_id       INT(11) NOT NULL AUTO_INCREMENT PRIMARY KEY,"
            "  filename     VARCHAR(255) NOT NULL,"
            "  name         VARCHAR(255) NOT NULL,"
            "  path         VARCHAR(255) NOT NULL,"
            "  parent_id    INT(11) NOT NULL,"
            "  dir_count    INT(11) NOT NULL DEFAULT '0',"
            "  file_count   INT(11) NOT NULL DEFAULT '0',"
            "  hidden       TINYINT(1) NOT NULL DEFAULT '0'"

Thumbnail creation for the directory is in
"./libs/libmythmetadata/imagethumbgenthread.cpp"

    // If a folder thumbnail shall be created we need to get
    // the real filename from the thumbnail filename by removing
    // the configuration directory and the MythImage path
    if (im->m_type == kSubDirectory ||
        im->m_type == kUpDirectory)
    {
        imageFileName = im->m_thumbFileNameList->at(id);
        imageFileName =
imageFileName.mid(GetConfDir().append("/MythImage/").count());
    }

For me it is not clear if a file is needed. Logic like *highlight* is not
found in the code anymore.

As Gallery will be using a DB in 0.28, I will wait with my adaptions till
after the release.
