Any new type of document not supported will cause error.

[sujith84]

My .csproj file contained a line of type EmbeddedResource. Since the library does not have support for this type, the enumeration of Contents instantly throws an error "Item not found in Dictionary". This could be solved by adding a class EmbeddedResource but more unsupported types can come up.

I have made ItemGroupContent a concrete class, and now if an ItemGroups Contents loads an element that does not have a class, it will be assigned an instance of ItemGroupContent.

CSProjectNode's ElementName is overridden to return the actual element name.

You should be able to access child elements through CsProjectNode methods.

I have also added EmbeddedResource as well.

Thanks!
