Fix inbox from, to, cc, and bc address text non-allignments

As I looked at the progress made so I far I discovered that when an item in inbox is clicked, the address shown in the From: and To: sections under the title of the inbox message title spilled over its <div> container.

This commit is intended to fix that and has been coded in a such a way that it can manage several addresses in each section going forward.

Cheers!
