Feature: Core Improvement Beta 27

[wpdas]

• extractSpreadsFromJSX removed. Its functionality is now part of extractPropsFromJSX;
• Added plugin (stateless_renamePropsTo__props__) to the cache system that changes any global property with name props from stateless components to __props__
  to prevent the parent widget property from being overwritten, thus correcting the conflict of
  properties that use the name props;
• Fixed the problem where when compiling Widgets, they received spreads more than once in their props.
