changes needed for the new GeoNode integration: add the new GeoNode plugins, add the dependencies, and update gxp
Added a plugin for displaying a layers history. it's a work in progress...
Added a geogit utilities plugin that can be used by other plugins associated with geogit.  Right now it is only used for checking to see if a layer is a geogit layer or not when it is added to the map
Changed the popup created for feature info to be a panel and docked it into the east panel.

This will probably need to be cleaned up a bit and is still a work in progress.
Modified VersionedEditor to use the GeogitUtil plugin.
Initial pass at showing feature diffs in the VersionedEditor.
The GeoGit history in the south panel will now  be hidden when the user removes a layer.
Initial pass at displaying ghost geometry for when a feature's geometry changed.
Merge commit '686fb974d084a38a39d0296eb0641673989de47f'
Added a call to geogit's diff when a cell is clicked in the GeoGitHistory panel.
Fixed removal of the diff layer, somehow didn't commit it last time.
Added a check to ensure it is a GeoGit layer being removed before hiding the history panel.
Right clicking on a layer will now give the user an option to show or hide the GeoGit history panel.

Fixed a bug with adding features.

It was trying to build a log call with the feature id of a feature that wasn't fully created yet. Added a null check for the feature id.
Initial commit of polygon orthogonalization.

Currently doesn't save unless you move a vertex manually first.
Minor fixes to the Attribute and History Panel.

Added quick fix for scroll bars to layer and attribute panels, changed title of attribute panel to the layer name, changed attribute panel to flex with panel.
Got the orthogonalized geometry push to the server by manually calling the drag handles on the points in the polygon being edited…  There is some duplication of code, but can make it nice later
