v1.7.0

• Added a frame remote control toolbar at the bottom of the app - next/previous image, power on/off, and switching the loaded playlist, straight from the browser, plus a current-image thumbnail. Supports multiple frames and multiple toolbar instances at once. Talks directly to the frame over your local network, so it needs a fixed IP (a DHCP reservation) and network access from wherever this app runs - can be turned off in Settings.
