Boost -> Catch Exercise Conversions

[arcuru]

Setting this up to track the total list of exercises that need to be converted. This is part of #233.

Here's the full list of exercises, not including the 2 open problems in PRs. I plan to work mostly top down according to this list, as this reflects the order that students will encounter the problems.

When I setup PRs I will be doing it in groups where it makes sense, probably with how they're grouped below. If nobody LGTMs, I'll leave the PRs up for at least a week and then push them myself unless I think there's something that needs more consensus. If I do get some LGTMs, I may push them faster.

I'm merging these in with 1 commit per problem, and doing a rebase and merge so that every commit is present in the master branch.

Every exercise now has an open PR, and each PR has a planned merge date in the description for either April 13th or April 20th, the next 2 Saturdays.

If you'd like to help, read over the changes made to the test suites and give a 👍 on the PRs if you don't see anything obviously wrong, or call out issues if you do. The only real way I could've messed up and not found it in testing is if I somehow deleted full tests or changed the test cases. I read all the changelists looking for that so I consider it fairly unlikely to have happened.

Gigasecond/Meetup will still have a dependency on Boost::date_time as discussed in #224, but everything else has 0 references to Boost.
