#12 "things" in plural named as singular

[Mikhail Miguel]

Unlike in Japanese language, in English (and various other Western languages) a 'S' is used on the end of the noun to describe plurals. I'm not sure, but the folder "\preload" and the modules "message", "profile" and "user" really means "preloads", "messages", "profiles" and "users" (just examples). Feature request: fix the new modules names before the 2.2 final release (messages and profiles/ profile editor).
