* Remove Bindable.
Fix Observable & ObservableArray tests
Fix formattedString text
Change implementation of Span, FormattedString & TextBase
properties valueChange called before native setter
* revetred formattedString tests asserts - formattedText update text property again
properties - when getting value we now use always property name instead of key (using key could return undefined for property that is set to its default value)
updated fontSize & fontInternal properties on all controls
fix font properties so that fontInternal is reset if the new font is the same as Font.default
* fix tslint errors
moved some native setters from TabView to TabViewItem.
shorthand properties converters now accounts for unsetValue.
better formatting for test duration.
Less than 30 erros left, let's hope it still works
Added lib.*.d.ts from typescript, removed lib and dom stuff, added by hand XHR, alert etc. .d.ts-es for polyfills
Roll back some changes involved in separating UIEvent for dom and ios
Test combined dts-es will now use lib, while internally we will not to avoid UIEvent conflict with dom stuff
