Takes **PhoenixmlDb.Core 2.0.0** (unchanged — Core runs its own cadence).

### Added

**The built-in list types are now cast and castable targets** (#74). XQuery 3.0 permits
`xs:IDREFS`, `xs:NMTOKENS` and `xs:ENTITIES` in this position even though a list type is not an
item type: the lexical form is split on whitespace and each token cast to the member type, so the
result is a **sequence**.

```xquery
"a b c" cast as xs:IDREFS      (: ('a','b','c'), of type xs:IDREF* :)
"a b c" castable as xs:IDREFS  (: true  :)
"1 2 3" castable as xs:IDREFS  (: false :)
```

These previously reported `XPST0051: 'xs:IDREFS' is not a recognized atomic type` — a true
statement about a list type and the wrong answer in this position.

### Fixed

**The `xquery` CLI printed a .NET type name for a function item** (#76, closes #75).

```
$ echo 'function($x){$x}' > q.xq && xquery -f q.xq
PhoenixmlDb.XQuery.Execution.InlineFunctionItem
```

`PhoenixmlDb.XQuery.Cli` carries its own `ResultSerializer` alongside the engine's
`XQueryResultSerializer`, and it had no case for a function item at all, so one fell through to
`item.ToString()`.

### Conformance

**W3C QT3 29,803 / 31,379 (94.98%)**, up 63 from 2.1.0's 29,740.

Worth stating how those 63 were earned, because not every conformance movement is the same kind:
**#74 implements the feature**, so the denominator stays 31,379 and the passes rise. That is
different from a harness-honesty fix, which raises the percentage by removing cases from the
count. Both are legitimate; only one of them means the engine does more than it did.
