Nustache ToolBar

Right click anywhere in the toolbar section and add Nustache Config Utility.

When starting visual studio the Local config settings will be defaulted to even if changing the config environment had been changed before.
Changing the dropdown will compile all configs within the current open projects branch to that environment.
If a new Environment is needed selecting [Add / Clone] will open a tool window allowing user to do just that.
Clicking the Button (Mustache) will open the main Tool Window

Colors
- Each color corresponds to status of the row and the status can be viewed by clicking the eye icon.
  - Pink: Row has empty value(s)
  - Green: Row has different value(s)
  - Yellow: All values are equal
  - Gray: Unused row (key)
  - Blue: New row (key)
Selecting a row will show all configs that contain that key.
Clicking a config will open it in an editor.
Column sorting will persist even after closing Visual Studio. Sorting can be changed ether in the tool window by dragging columns or by viewing the options in visual studio. TOOLS => Options => Nustache Configuration. NOTE: if the order is changing using the options window the update will not take effect till visual studio is reset.
