* Added getAdditionalSelectors function so that nativescript-theme can be functional again in NS 4.x
* Change to a better more extensible additional css system.
* removed redunant function on the name.
* Fix lint issues
* Adding mergeSelectors to the remove function
* Added test of new add/remove css functions.
* fix: revert testRunner.ts changes that disabled all tests except style
* refactor: fix typo
* chore: fix typo and change test to no not affect global styles
* Move the applyStyleFromScope to onLoaded, when the views are created and id or className properties are set the CSS selectors are queried and applied multiple times
* Condense the changes when applying properties
* Image corners were blinking in #4322 and CSS border will now draw non uniform corner radiuses if the border color is uniform
* Implement per-side corner radiuses for iOS
* Update stretch-mode example
* Update matrix-mode example
* Update image resources
* Add clipping for non uniform radii without border width, don't throw for missing image resources in css
Split type.class from CssTypeSelector to CssCompositeSelector, probably support type#id.class selectors
Apply review comments, refactor css-selectors internally
Applied refactoring, all tests pass, button does not notify changes
Add tests for the css selectors parser.
Added tests for css-selectors
Added basic implementation of mayMatch and changeMap for css match state
Implemented TKUnit.assertDeepEqual to check key and key/values in Map and Set
Watch for property and pseudoClass changes
Add one child group test
Add typings for animations
Added mechanism to enable/disable listeners for pseudo classes
Count listeners instead of checking handlers, reverse subscription and unsubscription
* 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.
