[Rails-devel] Cleanups

[Erik V. <eri...@hc...>]

I have noticed that XCode does warn about several classes marked as
deprecated (in your comments) that are still being used. But the deprecation
comment does not specify what should be used instead. Those might be a
better item to clean up then simply adding JAVA Docs.

 
I have cleaned up most of those, but also left in one that is only used in
the external tile XML conversion utilities. Too lazy now to rework that
code.
And cleaned up more code based on the compiler warnings. The remaining
warnings are inevitable, or refer to variables for future use or to the
remaining deprecated method. 
 
Erik.
