making easy bugs easier

[Martin Pool]

An idea:

If you see a bug that should be easy to fix (in both time and
knowledge of the codebase) but you don't want to do it yourself right
now then

1- tag it easy
2- more importantly, add a comment explaining _how_ it could be
tackled, for example

  easy: this could be done by wrapping os.rename in transform and
transforming OSError into a cleaner message; add a test in
test_transform

We have several people now working through small-medium bugs at great
rate and I think this would be an efficient way to stoke this fire.
