Add meaning for Wallpaper Search Subject string

Currently the translations for "Subject" in the Wallpaper Search
dropdowns shares a tc id with several other strings that have a
context of "subject of an email" which uses a different word in some
languages. The documentation for grit says that settings a meaning can
prevent 2 strings of the same English word from having the same tc id.
