Add a 'Paste from Word' plugin for editor

[Jared Jurkiewicz]

Cut and paste is a common function people use with editors. Unfortunately certain applications, such as MS Word tend to inject a lot of extraneous, and often bad, HTML into the Editor when pasted in.

The editor needs an intercepter plugin that allows for a secondary window to open where content can be filtered. That content can then be stripped of the garbage that causes Editor issues and injected as mostly clean HTML, this improving user experience with the Editor.

The secondary window is needed, as we cannot intercept native paste events, so the window will act as the intercept and then we know its source and what filters to run. I have a working prototype of this plugin now and it has tested well with severam word documents. I'll be comitting it in soon.
