Fix for #9 - XML doc comments on F# record type fields do not appear when accessing in C#

F# record fields are exposed as properties, and therefore need the "P:" prefix in their XML doc markup.  They were incorrectly being given the "F:" prefix. (changeset 1280439)
Fix for #69 - Invalid code generated when calling C# method with optional nullable args

Old codegen was improperly emitting default Nullable() for all nullable optional args that were not specified by the developer.  This was correct when the default value was in fact "null" (i.e. Nullable()), but was incorrect when default value contains a real value (i.e. Nullable(42)).  This change now detects when default value is a System.Nullable, and emits proper call to Nullable(xyz) constructor when required.  This change is based on suggestion form Vlad in email a while back.

Also noticed (from comment in the code) that VB allows byref optional args.  Upon investigation, these were also being handled incorrectly, so I refactored a bit in order to handle those. (changeset 1280456)
Adjust parser to disallow vertical pipes in active pattern case identifiers.

Related to #78 - without this restriction, the typechecker can't distinguish between valid pipes separating cases and invalid pipes that are embedded in a case identifier.  The result is that nonsense like this compiles, when it should not:

let (|``Foo|Bar``|) x =
    match x with
    | 0 -> Foo
    | _ -> Bar

match 42 with
| Foo -> "foo"
| Bar -> "bar" (changeset 1282321)
