dwpage.php: add an option to get metadata 

This adds an option to ./bin/dwpage.php, to display metadata about a
page. This is useful in maintenance shell scripts, and debugging plugins.
There is no ability to write metadata, only read them.

./bin/dwpage.php -u <user> gmeta [page] <meta tag>

where <meta tag> can be "date modified" (in quotes) or "last_change date"
an empty <meta tag> returns all metadata.
