Hristo Hristov 8d40782191 Style perf improvements (#2342)
* 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.
