Allow to enumerate/include redirects
E.g., apfilterredir in getPagesInNamespace and getAllPages (Allpages).
For example, getAllPagesInNamespace with all and getRedirectsInNamespace with redirects.
Another thing about redirects is noredirect in move.
So the idea here is that .getAllPages will support whether to include, exclude, or include only redirects? This is good as it currently only allows excluding, annoying.
There is a more general problem, all functions have hard-coded params (with only upload having extraParams), so one can find many issues, like this one, or https://github.com/macbre/nodemw/issues/133, or not being able to query sha1 (in revisions and image info), etc.
