Return null in case of no items instead an error.

Return a null in
Synthesis.FieldTypes.Adapters.AxesAdapter.SelectItems and
Synthesis.FieldTypes.Adapters.AxesAdapter.SelectSingleItem
Add _ in template path starting with number

Added a _ to the namespace parts generated that start with a number.
This happens in the case that the item name starts with a number.

* Modified PR fix by making it universal (e.g. passing null to AsStronglyTypedCollection[Of<>] will return an empty enumerable) instead of just for Select[Single]Item
* Normalized indents to match tabs standard
Normalized indents
