Add tooltip to questions

[j-rewerts]

Some questions can confuse people. One of the questions on the City of Edmonton You Can Benefit site is "What is your Household's Total or Gross yearly income? (check line 150 of your tax return) Option: If you don't know your gross income, multiply your monthly income by 12." Having a tooltip that can be hovered over to give more info would be helpful for citizens. In this case, maybe it could explain what your tax return looks like, where to find your income, etc.
