The result of the type function should be compared against the
string "table", not the global variable. This bug probably went
undetected until now, as "table" is also the global variable for the Lua
table library.

Users are reporting disappointment that using pairs on title objects
doesn't let them see the fields available. It's easy enough to add a
__pairs metamethod to allow pairs to work on title objects, so let's do
that.
The same can be done for mw.uri objects.
For mw.message objects, we can easily enough change the implementation
to be like mw.language objects, which doesn't have this problem.
For mw.site.stats, we may as well just remove the load-on-demand feature
since it will be demanded as soon as the environment is cloned for the
first module.

Fixed several accidental leaks to the global namespace due to missing
"local" declaration. Removed extension of the string table by mw.uri,
same justification as I5d0ddb70.
