A clearer picture picker

When you pick a picture, the search box had Upload and Pinterest buttons stuck right beside it — which made them look like they'd act on what you typed, even though they're separate ways to add a photo. Tidied up:

• The search field has a magnifier and searches as you type — nothing next to it implies "submit".
• Upload and "Pinterest link" now sit in their own "or add from" row, clearly alternatives.
