Velocity of swipe open/close animations matches gesture speed.

Improved ViewDeck swipe open/close animations so that the velocity
of the animation after swiping now more closely matches the user's
swipe velocity.

Previously, the animation timings were constant and independent of
swipe velocity. Also, on swipe to close, the animation would stutter
at the beginning due to the ease-in timing.
added another panning mode that's conditional based on whether the left or right controllers are open or not.

Conflicts:
	ViewDeck/IIViewDeckController.h

Fixed it too.
It only worked when the panners where added when the view was open. The check is now made when the delegate kicks in.

Closes #109.
Fixed developer signing identity.
Added demo for IIViewDeckNavigationBarOrOpenCenterPanning.
Added IISideController.
Bunch of fixes in IIWrapController. Unfinished.
Exposed ledge and view sizes convenience properties.
Use screen bounds as reference fallback as long as the referenceView is not set.

Not perfect, but it will work in most use cases.
Fixes an issue with _maxLedge being set after rotation, when it shouldn't.

Fixed #209.
Updated VERSION.
Adding readme updates for orientation section.
Add center view panner when reseting center view
IISideController doesn't animate frame changes.

You can turn this off by setting animateShrink to YES.
IIWrapController forwards messages to the wrapped controller if it listens for them.
Some rotation support fixes in IIWrapController.
Include top and bottom controller in viewDeck.controllers.
Rotation support fix.

Arrranges subviews before delegating the rotation call to subcontrollers.
Improved rotation support.

There's a new delegate call which allows the delegate to adjust the ledge before it is set.
When the viewdeck is open (aka "on a ledge") and it is rotated, it takes the ledge size instead of the relative offset size.
Added previewBounce methods and delegate calls. Also added necessary QuartzCore framework to project.
