Additional error information in the event of a COM error.

[Antony74]

Example:

var win32ole = require('win32ole');
var db = win32ole.client.Dispatch('ADODB.Connection');
db.Provider = "Microsoft.Jet.OLEDB.4.0";
db.Open("nofile.mdb");

Output:

OLE error: [Open] -2147352567 [Open] = [10]
Microsoft JET Database Engine: Could not find file 'D:\git\nodejsplay\nofile.mdb'.
(It always seems to be appeared at that time you mistake calling'obj.get { ocv->getProp() }' <-> 'obj.call{ocv->invoke() }'.) IDispatch::Invoke AutoWrap() failed

TypeError: node_win32ole::V8Variant::OLEInvoke failed

This suggested patch may also help to address issue #5

Hi, Antony74.
Thank you for your code. I merged it.
And you may use 'wcs2mbs' or/and 'WCS2MBCS' in ole32core.cpp for your language locale of console and variable length string. (sample is 'Method_printACP' in node_win32ole.cc)
