Removed unneeded assets for GWT module integration.
Added a .gitignore file.

This is the standard .gitignore file for most of the iPlant GWT modules.
Added a Maven POM file and updated the GWT XML file.

Removed the entry-point and theme inherit since this is now a library project.
Merge branch 'master' into integration

Updated some CSS for the DE integration.

Removed the grey background color of the pipeline workspace.
Changed the app-drag-insert dashed-line color to blue so it stands out against a white background.
Added a large z-index to the tooltips so they can stay on top of GXT windows.
