Track solutions in master

[milesfrain]

There are lots of maintenance benefits to tracking solutions in the master branch. I'll make that conversion after #140 and #144 are merged, and if there are no objections.

The plan is to:

• Keep solutions in test/no-peeking/Solutions.purs
• Track a blank test/MySolutions.purs
• In test/Main.purs:
  • Import both Test.NoPeeking.Solutions and Test.MySolutions
  • Start with all exercises uncommented
    • This will enable easy CI

Then instruct readers to:

1. Delete the import module Test.NoPeeking.Solutions line
2. Block-comment all tests
3. Add their solutions to Test.MySolutions.purs
4. Uncomment tests as they solve each exercise

This new process makes things a bit more annoying for readers by adding steps 1 and 2.

If we're planning a processing step in CI to strip out anchor comments in #90, we could also automate steps 1 and 2 above so the reader doesn't have to do these manually.

@milesfrain Just caught this: the solutions should be kept in test/no-peeking/Solutions.purs, not test/no-peaking/Solutions.purs.

@milesfrain In instruction 1 above, change code to import Official.Solutions instead of import module OfficialSolutions.

Went with Test.NoPeeking.Solutions in #168 and edited original post.
