Initial check-in for the 1.1 release, fixes include:

* Update to Line Renderer - updated scrip plus patches, now more code friendly for adding points
* New Curved Layout component
* ScrolTo script updated based on authors new version
* UISoftAlphaMask updated to latest version
* Added ScrollSpeed to Horizontal and Vertical Scroll Snap
* Added Scroll Conflict Manager (untested)

ToDo:
* Test Scroll Conflict manager
* Make the distance between pages on the H&V Scroll snaps configurable
* Test Scroll Snap starting page fix
* Review Reorderable List scrolling issue
* Review Reorderable List Worldspace render issue
