Add option to store tool references and use with Bind() in generated Python code

Currently, tool references are not stored at least when generating Python code. Tool ID’s cannot be used when binding events to handlers.

self.frame_toolbar.AddTool(wx.ID_ANY, "Help", wx.Bitmap("help.png", wx.BITMAP_TYPE_ANY), wx.NullBitmap, wx.ITEM_NORMAL, "", "")
...
self.Bind(wx.EVT_TOOL, self.onHelpClicked, id=wx.ID_ANY)

Preferred way would be to have an option to store references and use them with Bind(). This would be consistent with how menu items are handled.

self.helpTool = self.frame_toolbar.AddTool(wx.ID_ANY, "Help", wx.Bitmap("help.png", wx.BITMAP_TYPE_ANY), wx.NullBitmap, wx.ITEM_NORMAL, "", "")
...
self.Bind(wx.EVT_TOOL, self.onHelpClicked, id=self.helpTool.GetId())

Fine. I will add some test cases and then integrate it into the master branch. I will put the optional (attribute) names on my todo list, but not with high priority. (Maybe someone volunteers for this.)
