Title: {SD}List [front|back] primitives

Just some minor details:
* Adding {front|back} assign for DList and DList.Range (they were missing).
* Added a few missing ddocs.
* A few missing enforcement checks:
Arguably, we *may* want to change some of the enforcements into asserts, but right now, some methods from XList.Range had nothing, whereas the underlying XList had enforce. This was inconsistent.
