* Add location information to ANCM hosting doc
Fixes #1931 ... also updated capitalization of "h" of `applicationhost.config` to `applicationHost.config`.
Adds ANCM module, schema, and `applicationHost.config` locations to the doc for easy dev reference.

* Minor update
Consistency: `IIS Express` (with space) is better than `IISExpress`.
