added the missing fields and improved the translation

The "settings" links in the Getting Started section (or, if #399 were to happen, "more" menu) and compose sections are now different; the "compose" link is "Edit profile," while the one in the Getting Started section is now "Preferences."

All languages have been updated to accommodate this, based on the existing usages of these phrases in language files in the Rails part of the app!
