Fixed regression with WidgetModality's mask not being re-aligned. For some reason WidgetModality's `scroll` event subscription stopped working in 3.5.0 which did work in 3.4.1. This changes the event subscription to explicitly attach to the `window`: From `Y.on('scroll', ...)` to `Y.one('win').on('scroll', ...)`. The conditional to check whether this scroll listener should be attached has been updated to only include iOS < 5 and Android < 3 because the newer versions of these OSes _actually_ support `position: fixed;` natively. Whereas the previous versions would pass the feature test but not actually support `position: fixed;`. Fixes #2532002

Fixed WidgetModality regression when using modal and non-modal panels. The masking was being displayed even when the panel being shown was configured to not be modal. Fixes #2531853

Cleaned up any messy areas of WidgetModality that I had to look at. Added manual test for multi-modality.

Squashes multi-modality bug. Fixes 2531484, 2531812, 2531821

Fixed WidgetModality's initialization logic to always run. If a widget was not constructed with `{modal: true}`, WidgetModality's initialization logic would not run, which is wrong, and it is now fixed. Also, the initialization logic has moved from the constructor function to the `initializer` method. Fixes #2531401

Updated WidgetModality to use `Y.config.doc` instead of `document`. Changed references from `document` to `Y.config.doc` in the `supportsPosFixed` feature test. Fixes #2531220

Formatting WidgetModality code.

fixed Y.WidgetModality constructor to avoid requiring config object

Fixed stacking issue with multiple modal Widgets, along with various syntax errors found in widget-modality by running JSLint. Fixes #2530953

namespaced @property/@method cleanup Some files had new YUI.add() metadata property ordering, resulting in new -min files. No functionality was changed.
