Removed generic UL/LI content CSS from scrollview-base.css. The rules were too broad, and scrollview is supposed to be content agnostic anyway, so wanted to avoid the idea of add code to mark LIs through JS. The rules have been moved to the examples where required (e.g. horizontal lists as scrollview content). Fixes #2529418

Fixed IE7 scrollview missing content. Fixes #2529260. Tested all scrollview examples on IE6,7,8, FF 3.6, Safari 5, iPhone emulator and android emulator

Removed loading CSS from scrollview

Fixed IE text selection. Fixes #2529249

Added default rule to hide scrollview

CSS tweak: rolled basic ul/li content rules from examples.css into scrollview-base-core.css as the common case, so that it looks ok out-of-the-box.

Simplified scrollbar impl for IE

Integrated non-native transition support for scrollbars

Scrollview cleanup, extracted overflow handling into class

Moved scrollview from sandbox to src. Basic functionality working on desktop and mobile devices.
