Pre-Release v1.2.1-pre1

Includes the Following Changes;

• Moved setup functions into a seperate file, textAngularSetup.js. This file must be included before textAngular.js file. Using the defaults and textAngular.min.js causes no changes.
• Adding the Image and Link click popup functions.
• Adding ability to drag and drop files into the editor.
• Manager now can add and remove tools dynamically.
• Added Custom Renderers adding the ability to use placeholders, eg an image, in the editor and display something else in display mode. Uses factory function taApplyCustomRenderers to do this.
• Added option to change the default wrapper tag.
• Basic format stripping on paste - removes all HTML and word tags.
