Better name for wxXmlResource::GetDirection() argument.

'dir' is not very descriptive (of course it's a direction!), it's better
to include 'default' in the name to indicate this is the default value
to use in absence of a specific one.

Fix incorrect XRC format docs for wxMenu(Bar)'s "style" property.

It is not true that no standard properties are allowed, "style" is.

Minor corrections to XRC format description.

Don't lie about wxImageList in XRC format spec.

The documentation for setting image lists on controls was a complete
fabrication.  It pretended that image lists were created as child
<object>s, while in reality they are properties just as e.g.  fonts are.
Fix this and also better document the related 'image' property.
