We can resolve this FIXME.

Done, but the type conversions needed to be able to allow such a direct
assign()ment was a bit fiddly to get right.

Ended up adding a WebNode constructor for Oilpan to handle this, please let me
know what you think. The cleanest solution I was able to come up with.

(As the FIXME in the header file says, the reference arg could be given the more
precise type WebVector<WebElement>, but changing a public API is best done
separately.)
