Bug 336843 - Attach files to Transactions

[Patrick]

Christian/List,

I found a few cycles today and converted to KVP.

Updates:
- URI is now stored in KVP instead of the Transaction struct. This should
maintain compatibility with existing installations. (Per John Rails'
suggestion.)
- Split menus and dialogs for storing a file link vs. a location link.
- Added menus to right-click in addition to top menu
- Added UNTESTED code for Mac and Win32. I think it's close but I have no
way
to compile/test.

Patch is uploaded in Bugzilla.
