Updating to GWT 2.5.0-rc1
Added the DiskResourceServiceFacade interface
Disk Resource window gxt3 refactor, initial commit
Implemented icons, text, and clickhandlers for disk resource toolbar.
Also adding the disk resource presenter unit test with jmock.
Large update to DiskResourceWindow GXT3 refactor.
DiskResource view (incl toolbar) are created and ready to be styled. 
Created specific dialog for File selection and folder selection.
Began implementing unit tests (JUnit, not GWTTestCase) for the presenter.
Data window refactoring, cont
Added definitions for new service calls which combine previous service calls which were previously split into 2 separate endpoints, one for files and the other for folders.
Porting of callbacks has begun in earnest. Next, the underlying framework will be in place.
Further Disk Resource GXT3 port
Implemented renames and deletes of disk resources, as well as folder creation. Unit tests need to be implemented for creation and renames.
More Disk resource window port to GXT3
Implemented dependency injection with GIN in order to create a singleton Tree object which is injected into every disk resource presenter's view object. This essentially creates a client side data store for caching disk resource data retrieved from the server. It currently caches all files and folders retrieved from the server.
Updated unit tests.
Updated upload/download events
Ported disk resource metadata window to GXT3
Refactored the Disk Resource dialogs.
The Create folder and rename dialogs now take in a presenter, and call the presenter when the action is initiated instead of calling the service directly.
Additionally, corrected an autobean serialization issue with retrieval of metadata.
Integrated new Integrated the new unified disk resource endpoints 
Also updated to GWT 2.5 proper (not release candidate)
Implemented Drag N' Drop for Disk resource view.
Still need to test integration with the "move" disk resources endpoint. Also need to verify that drag and drop is appropriately restricted in accordance with user permissions.
Merge branch 'master' of https://github.com/iPlantCollaborativeOpenSource/ui-disk-resource-module into gxt3-sandbox
Implemented drag and drop on disk resources
Actions after success call to "move" endpoint need to be finalized.
Corrected preview selection on files (only on hyperlink, not on cell)
Updated pom versions for the GXT3-Sandbox branches
Beginning to implement new error handling for disk resources.
Migrate Disk resource callback error handling to ui-commons 
Needs to be tested.
Using autobean categories, the specific user feedback message for each error autobean is constructed. This is essentially the same as the DiskResourceServiceCallback from the DE, but with the obvious differences such as type safe error code objectification.
