Add word count to the section table

[andrasfuchs]

Some sections in some books are really short or just placeholders, and it would be great to have the ability to skip them on the "Select Sections to Split Off" screen. It could be done easily if we had a new column with the approximated number of words in each section.

Adding a column is easy; actually counting the words in each section is more difficult.

Each 'Section' is a TOC entry (or file start) that may be a complete file or an anchor inside a file. Look inside most Gutenberg epubs for examples of the later. The only way to define when a section ends with anchor entries, is where the next section begins.

To use the Calibre word count routines I have available, EpubSplit would effectively have to split every section into a new ebook first. The existing 'Get Size' button does basically that--it generates the split epub to determine the size.

A byte count for sections that are files might be more feasible.

I'll leave this open for now, but I don't anticipate implementing it.
