Bug 15555 – [Reg 2.070.0-b1] Hidden error cause by Throwable.message

Compiling Tango with DMD 2.070.0-b1 causes the following error: tango/text/xml/SaxParser.d(808,8): Error: class tango.text.xml.SaxParser.SAXException use of object.Throwable.message() is hidden by SAXException; use 'alias message = Throwable.message;' to introduce base class overload set The error is due to the new method "message" in Throwable, which is causing a conflict with an already existing method in a subclass [1]. PR that added the new method [2]. [1] https://github.com/SiegeLord/Tango-D2/blob/d2port/tango/text/xml/SaxParser.d#L861 [2] https://github.com/D-Programming-Language/druntime/pull/1445#issuecomment-170530377

We've reverted the addition of message for now, up to discuss a better design. This doesn't mean we won't be introducing a message method in a later release.
