Add XML mention to WP import instructions

[rosso99]

When exporting from WordPress, there is mention of both an .XML file and WXR:
"When you click the button below WordPress will create an XML file for you to save to your computer.

This format, which we call WordPress eXtended RSS or WXR, will contain your posts, pages, comments, custom fields, categories, and tags."

But when you import a WP file, there is no longer a mention of .xml - I think this is confusing for novice users (I just walked one through the import) as they have a .xml sitting on their computers:

"Upload your WordPress eXtended RSS (WXR) file and we’ll import the posts, pages, comments, custom fields, categories, and tags into this site.

Choose a WordPress WXR file to upload, then click Upload file and import."

I suggest adding a line to the import text like:

Choose a WordPress WXR file (this file will end in .xml) to upload, then click Upload file and import.

patch for wording change

[rosso99]

I made the change by adding (.xml) into the wording:

"Choose a WordPress WXR file (.xml) to upload, then click Upload file and import. "

This should be easy to apply to all branches since it won't require further translation but rather just insertion at the proper point.

In the future please upload patches as .patch or .diff so we get the full syntax highlighting. Congrats on your first patch :-)

Ah, sorry didn't know about that .diff - best to update our Codex - it says:
​http://wordpress.org/download/svn/

"You can output this to a file by using redirection:

svn diff > my-patch.txt"

I will see if we can add underneath that:

"If you're submitting a patch for review to Trac, be sure to use .patch or .diff as the file extension so full syntax highlighting is preserved."

Fixed and currently deploying.
