Revert commit d818575966e2e2000fe2b7ee390c620f595d9825

This reverts the commit that deprecated the with statement and added
a note to the docs that binding expressions will be compiled in strict
mode in Qt 5.2.

It turns out that we had to keep the with statement and enabling strict
mode breaks just too much unfortunately.
