This Cordova `ensureDevBundleDependencies` function will utilize a another
method called `ensureDependencies` which checks to see if a module can be
resolved by the tool. If it cannot be resolved, it will install it using the
`installNpmModule` facilities of `meteor-npm.js` in the same way as other npm
packages within packages, except with the destination as the `dev_bundle`.
This commit also adds a couple of previously not explicitly installed npm
modules which Meteor requires directly: `cordova-registry-mapper` and
`cordova-common`. Both of these were previously relying on npm package hoisting
which previously occurred during the installation of `cordova-lib` in the dev
bundle which happened under the supervision of a `package.json` file (which is
later purged).
When `cordova-lib` is installed directly, without a package.json, the
aforementioned packages are not hoisted to the top level, but instead reside
inside `cordova-lib`. This is less than ideal since we're relying on the API
of an indirect dependency of `cordova-lib`.
