Highlight the words corresponding to each identified term in the original text

[marta-]

Once the user hits Analyze, replace the textarea with formatted text where the words corresponding to terms are marked with a specific background color. Hovering the markings should highlight the corresponding term in the results list, and hovering a term should highlight (more, with a brighter background color) the source words. Use colors from the configured colortheme, avoid custom colors.

Also, Analyze should become Edit after the extraction is completed, allowing to go back and modify the text.
