Add ignore file to ignore Xcode cruft.
Exclude README.txt from the copy build files phase to eliminate a warning.

Actually, all the text files could (and perhaps should) be removed from this phase.

fix #57

Changed all sensor status messages lower case.
Fixes #84.

There are two issues:
* The centerGrid property of the GMGridView was never disabled, and instead we were calculating the left offset and animating left all the grid elements, which wasn't necessary.

* GMGridView does a two-stage animation, but does so incorrectly.  The second stage of the animation is in the completion block of the first animation.  Animations happen in a separate thread, so once the second animation starts, the completion block returned and we then updated the backing store, which modified the contents of the grid being animated...and then called another animation.  These three steps produced a very weird animation.  It would be better to fix this in GMGridView, but since we don't want to touch third-party code, set a timer to wait until the entire animation is finished before modifying the backing store.

Fixes #67

Added a red overlay with (currently not styled) Cancel and Confirm Delete buttons.  The cell itself becomes modal, but touching anything outside of the cell will cancel the delete action.
Fixes #85.

Nudge annotation button 2 points south.
Start of replacing the caution icon with a badge.
Fixes #82.

Eliminate the outlet for annotateButton, as the only reason we needed it was to set the image inside.  Set the image statically in the NIB instead.  This removes the annotate + caution icon.  A separate icon may be unnecessary since the popover is directly attached to the modality featuring a badge, added in 841f49ae1e5916f3a4f8000c66cf6b3b2907f08c.
Fixes #56.

The `editing` property of the cell gets set to NO by the GMGridView after you delete a sensor, and since that is the superclass, the subclass WSPersonTableViewCell's mutator which sets the style of the `editButton` doesn't get called.  Fortunately, the `editing` property doesn't matter for the operation (more of a formality), so ignore it and set the style based on the `selected` property of `editButton`.
Fixed bug where when highlighting the editButton with "Done" caption displayed the wrong caption and color.
Changed delete image animation in Capture Controller.

Instead of sliding the delete confirmation from the side and block the
entire application.  It is only showing up in the capture controller.
Fixes #68.

* Add a TapGestureRecognizer to the containing window to detect only taps that are no on the frontmost view.  If detected, dismiss the modal dialog.
* Remove existing cancel buttons.
Fix crash where `sensorCheckTimer` would continue to run after the `DeviceSetupController` was removed (press the back button within 3 seconds).
