Add colon after "Upload/Insert"

[neovita]

I walk dozens of new users through the WordPress interface and every once in a while I find areas where we can easily improve usability.

New users often have a hard time finding how to upload an image. I see them regularly click on "upload" and "insert" they don't realize they need to click on the icons to the right of upload/insert.

The fix is super easy, just add a colon after upload/insert. That will indicate that it is the icons to the right and not the words themselves that allow users to upload images.

Other solutions include adding a bit of color to the icons and/or making upload/insert a link.

Not that I don't think it'd pass, but this should have had feedback first.
