Typos/Grammar errors in profile.module upgrade

As part of the profile.module enhancement, a couple typos/grammatical errors were introduced. Below is a list of the ones I noticed, and suggested corrections.

• profile.module
  • "Because the form name's usage, spaces or any other special characters except dash (-) and underscore (_) are not allowed. An example for, name is 'profile_favorite_color' or just 'profile_color'." => "Spaces or any other special characters except dash (-) and underscore (_) are not allowed. An example name is 'profile_favorite_color' or perhaps just 'profile_color'."
  • "Display this field on member listsings" => "Display this field in member lists"
  • "A list op all options." => "A list of all options."
• user.module:
  • "Upload picture or picture" => "Upload picture"
  • In general, I think I liked the term "avatar" better than "picture." "Picture" seems exceptionally general and doesn't really suggest to users that the image will appear next to their posts. Additionally, in my interpretation of English, "picture" and "image" are synonymous, so phrases like "Failed to upload the picture image" (from user.module) make little or no sense. That's just my opinion, though; I can always use translation to change this on my sites.

I can provide a patch upon request if you feel my changes are reasonable.
