Change definition of "words"

It makes little sense to always remove punctuation and numbers
for words, while terms may include such characters. Always apply
all selected processing steps except stemming and stopwords removal.
Update the docs accordingly, and improve the definition.

More consistent with other processing options.

Fix active/inactive states for clustering

"active" does not mean what it was supposed to do, but rather
that the widget has the focus.

Stop printing CA results after running it

Printing can take longer than computing it, and it's pretty
hard to read anyway. Users can export it if they want, and
typically plots and the results window are more useful tools.
