Add a "Clear Formatting" feature

I want to add a new feature under the menu Tools > Clear Formatting that clears any formatting currently applied to the text.

Start by locating the Tools menu and the existing text-formatting behavior in the WolfEdit codebase. Define which formatting properties the command must clear, then verify that Tools > Clear Formatting removes those properties from the selected or current text without changing its content.
