I had somewhat rashly removed operator = in [r6280]
But since c++11 implicit defined copy assignment operator is deprecated when a user-declared destructor exists.
Still... alternative would be adding copy assignment operator but neither that nor the virtual destructor seem to be needed.
So rather removind destructor which seems to add an unnecessary virtual function table for it (seems to be just used like a POD throughout the code)

They all just implemented the same the default functions do.
This causes now warnings with newer gcc -Wdeprecated settings (otherwise they would have had to implement always both, but makes no sense as they did nothing special).

Usually something like __IRR_SOME_GUARD_INCLUDED__ replaced by IRR_SOME_GUARD_INCLUDED.
Removing underscores at the end wasn't necessary, but more symmetric (probably the reason they got added there as well).
While this touches every header it shouldn't affect users (I hope).
Also a few whitespace changes to unify whitespace usage a bit.
And a bunch of spelling fixes in comments.
