upload.js should reference parent instead of top

[huwr]

line 267 of wp-admin/js/upload.js:

if ( !win )
win = top;

breaks when wp-admin is within a master frame. for example, a cms system may use WP as one component while keeping a CMS navigation frame at the top. this javascript would reference the navigation frame, not the correct WP frame.

this can be fixed by:

if ( !win )
win = parent;

which will reference what it was intended to within any frame hierarchy.
