addon/info: wesnoth_addon_manager wants the dependencies list in _info.cfg
wam: Write title and type fields to _info.cfg like the C++ client does
wam: Make our _info.cfg's look identical to the C++ client's

To achieve this, add the same leading comment section ("do no edit this

don't use quotes around the uploads attribute value (it's an integer).
