File viewing Cordova fork artifacts

Tommy implemented fixes for cordova Filetransfer.download arguments, to enable proper binary file downloads on earlier Android versions (which don't support xhr2). Until the Cordova 2.6.0 release, when Tommy's developments will be integrated, fetch and situate the artifacts:

1. Visit Tommy's SpiderOak share room, click on the SpiderOak folder to expand its contents, and hit the Cordova subfolder's Download button to fetch the artifacts as a zip file.
2. Unzip the Cordova archive somewhere.

• [The following steps assume you've run 'cordova platform add android' to have the android platform directory]

3. Replace ./platforms/android/libs/cordova-*.jar with the one in the downloaded zip (will be 2.5.0 until we can pull master with the changes).
4. Replace ./platforms/android/assets/www/cordova.js with the one in the downloaded zip.
