[Win] A few final cleanups to the DataObject classes

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Brent Fulgham]

While working on Bug 131631, we noticed a few improvements that could be made once the Vector class had been updated with additional move-handling operators.

1. Use "someVector.last()" rather than "someVector[someVector.size() - 1]"
2. Use Vectors "takeLast()" method, rather than the hand-coded implementation in these classes.

Should be takeLast, not last/removeLast.

Should be takeLast, not last/removeLast.

Whoops! Left some unrelated debugging code in my tree.

[Brent Fulgham]

Anders, do I need to add a std::move() in these uses of takeLast to ensure proper move semantics?
