tictactoe: Fix type confusion.
...
With the new Map, we want to make sure we
convert the square number into an int.
The symptom here was you'd click on the
square, and the data would get passed
around via the event system, but when
we went to draw the board, the idx value
was a string.

js: Automatically convert var to let and const in most files.
...
This commit was originally automatically generated using `tools/lint
--only=eslint --fix`. It was then modified by tabbott to contain only
changes to a set of files that are unlikely to result in significant
merge conflicts with any open pull request, excluding about 20 files.
His plan is to merge the remaining changes with more precise care,
potentially involving merging parts of conflicting pull requests
before running the `eslint --fix` operation.

app: Prepare JS files for consumption by webpack.
...
This commit prepares the frontend code to be consumed by webpack.
It is a hack: In theory, modules should be declaring and importing the
modules they depend on and the globals they expose directly.
However, that requires significant per-module work, which we don't
really want to block moving our toolchain to webpack on.
So we expose the modules by setting window.varName = varName; as
needed in the js files.
