Rename all-packages-size.html to all-packages.html

It makes no sense to split the packages table into size and dependencies information until we can provide graphical presentations of the data. So the renaming reflects the fact that for the moment we will  have a single all packages table.

Remove all-packages-size.html and change filter icon

Remove all-packages-size.html, which has been replaced by all-packages.html. Remove all references to all-packages-size.html to avoid broken links and change the icon of the filters button to icon-filter in all-recipes.html, all-tasks.html and index.html
