Finally Health Bars!

We have health bars for all units and structures!

Also thanks to SamMhundy for the code to click and drag the Camera. This can be customized in options screen. Setting it to 0 will default to previous tap edges to scroll the camera.

Settings are now saved and loaded automatically.

PC Port updated to 1.5.7 as well! Please keep in mind this is just a unofficial port so the control scheme and UI is still based on the Android version.
