Redundant given this is the project-wide license already,
especially in file headers that already include the GPL license
header.
This and other minor fixups based on feedback from Ie0cea0ef5027c7e5.
* Add @file where missing.
* Move @ingroup and @deprecated from file to class doc where needed.

Up until now, the import backend has tried to resolve titles in the XML
data using the regular Title class. This is a disastrous idea, as local
namespace names often do not match foreign namespace titles.
There is enough metadata present in XML dumps generated by modern MW
versions for the target namespace ID and name to be reliably determined.
This metadata is contained in the <siteinfo> and <ns> tags, which
(unbelievably enough) was totally ignored by WikiImporter until now.
Fallbacks are provided for older XML dump versions which may be missing
some or all of this metadata.
The ForeignTitle class is introduced. This is intended specifically for
the resolution of titles on foreign wikis. In the future, an
InterwikiTitle class could be added, which would inherit ForeignTitle
and add members for the interwiki prefix and fragment.
Factory classes to generate ForeignTitle objects from string data, and
Title objects from ForeignTitle objects, are also added.
The 'AfterImportPage' hook has been modified so the second argument is a
ForeignTitle object instead of a Title (the documentation was wrong,
it was never a string). LiquidThreads, SMW and FacetedSearch all use this
hook but none of them use the $origTitle parameter.
