TYPO3 Core

htmlArea uses class HTMLArea.Base in order to provide a class extension mechanism for creating plugins (an adaptation of a script authored by Dean Edwards http://dean.edwards.name/). This is not required anymore as ExtJS provides such class extension mechanism.

Attached patch thus removes this class.

Plugins need to be defined in a new way, described in the htmlArea RTE API Manual. A compatibility bridge is provided until TYPO3 4.8. However, this may break plugins that extend other plugins and make use of this.base(). Invoking this.base() from any method used to invoke the corresponding method of the parent class. this.base() now invokes only the constructor of class HTMLArea.Plugin.
