[SECURITY] Fedora 20 Update: geary-0.6.3-1.fc20

Geary is a new email reader for GNOME designed to let you read your email quickly and effortlessly. Its interface is based on conversations, so you can easily read an entire discussion without having to click from message to message. Geary is still in early development and has limited features today, but we’re planning to add drag-and-drop attachments, lightning-fast searching, multiple account support and much more. Eventually we’d like Geary to have an extensible plugin architecture so that developers will be able to add all kinds of nifty features in a modular way.
