  * summary:  array_shift() Error on WXR Import => WXR import error when no
              tags are used


 This occurs because the 'tags' variable is only casted into an array once
 a tag has been found.  If the blog owner has never used tags before, this
 causes a problem.  This patch initializes the 'tags' variable as an array
 at the beginning of the import class.

 To recreate:

 1) Have 2 fresh installations side by side.

 2) Export content from 1 WP instance from Manage>Export

 3) Import that file on the second WP instance from Manage>Import>WordPress

 *) Then try again, but give Hello World a tag.
