Be a party-pooper; No more Akismet Dancing upon upgrade; Respect custom WP_CONTENT_DIR for bundled plugins/theme installation; Respect custom WP_CONTENT_DIR/WP_LANG_DIR for Language files when upgrading; Standardise WP_Filesystem path method returns (They're trailing slash'd). Adds an exclusion list to copy_dir() as well as WP_Filesystem_Base::wp_lang_dir(). See #14484 See #11495
