Description
When using the PDFPlugin pdftohtml to generate HTML for the HTMLPlugin to extract text, there is a flaw with multi-column pdfs. In the simple version (currently used by Greenstone), text is extracted left to right, ignoring columns. This results in correct HTML where text is aligned properly for viewing, but the text is not in a logical order. When the text is extracted, the content of the columns are interleaved line by line. This can be fixed by adding the '-c' option on pdftohtml when called. This has the added benefit of providing additional structure that can be extracted (sections, etc.)

Can -c go on all the time? What if there are some docs with columns, some without? Can it go wrong?
