Major rewrite and suggestion to reduce country-specific details

I have begun to improve the article by removing unsourced statements, reflections and opinions, as well as doing some housekeeping (e.g. repairing broken links, bringing lists in alphabetical order etc.). More work clearly needs to be done. The structure could certainly be improved, although I am not yet quite sure how to best do this. A clarification about what is included in water privatization and what probably not (e.g. bottled water, markets for water rights) could also be useful, although there may be no consensus on where to draw the boundaries. I am also planning to add a table with all the 30 or so countries that currently have private water concessions or similar contracts, which I hope will be useful. Keeping a neutral point of view is extremely important and any constructive, good-faith advice on how to ensure this on such a controversial topic is welcome. Finally, I would suggest to remove the country sections and refer the reader to the respective country-specific articles on water privatization.
