ubercart 5.x-1.5

This release fixes a few bugs (including one long-standing issue that we were able to resolve thanks to support from Acquia) and adds in three notable features:

1. IP addresses will be logged for orders to help store owners address cases of fraud.
2. The checkout enhancements contribution has been rolled into core to help prevent duplicate checkout review form submissions.
3. torgosPizza contributed a patch correcting the headers for file downloads that allows browser to resume paused downloads.

For more information, see the news post on Ubercart.org.
