[Ironruby-core] accessor methods and property syntax in .NET

if i do that, calling bar as a property like this:

var value = myObject.bar;

leads to 'value' being an instance of IronRuby.BuiltIns.RubyMethod, and not
the value that is in the @bar instance field

which

i'm using 1.1 btw, not sure how this would behave on 1.0

from looking at the IronRuby source code, it looks like i need to find a way
to change the RubyMemberInfo for a given accessor method to
RubyAttributeReaderInfo or RubyAttributeWriterInfo
