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
* Add css-perf app.
* Style properties now check only properties that are set.
Image utils module required on top (instead of in onMeasure) to improve performance.
Remove try/catch block when Style applies native property.
* fix tslint
* Fix broken merge
Update package.json version
* Failed miserably - if the try/catch around applyProperty method is removed - TextField fails big time.
TextField needs some good refactoring as well as calls to _updateTextDecoration & _updateTextTransform
utils - setTextTransform & setTextDecoration should be split, typing support should be added.
