Change what gets displayed when emailing invoice and paypal gateway.

Change what gets displayed when emailing invoice and paypal gateway.

In this case, a picture is worth a thousand words.

One screenshot is my inbox.  I'd like to change what the From/Sender field displays.

The other screenshot is what happens after you click the pay online now link in an emailed invoice.  I'd like to change the product description.

Currently, the field I want to change show my name.  I'd like to change them to show my company name.  I'm sure it's an easy thing to do, I just haven't ran across it yet.
