Compiler should be more supportive of lowercased namespace qualified Accesses

[hopscc]

See discussion around wx.NET and access to types qualified with 'wx.'
 WxWidgets/wx.NET and specific problems with using qualified Types from that (any)
(lowcase named) namespace -  posting.

This isnt a failure of the lookup or of case translation between cobra and the Library, if the ns qualification isnt correctly cased (CapCased) the compiler doesnt even attempt to resolve and emits a 'cannot find Type error' - it could do better which would correct most of the inconsistancy around the current handling of this (admittedly edge case, wrong lib naming practise) issue.

Support specification of lowercase namespaces for Types.
patch, tests, relnote.

Also take opportunity to remove unused param passed to Compiler.symbolForName.
