This reverts commit 59bb2dba.

Uses the `version` property from the `pubspec.yaml` file to set the corresponding fields in the `local.properties` file respectively in the `Generated.xcconfig` file.

The `--build-name` and `--build-number` options have changed. Now they trump the `version` property from the `pubspec.yaml` file.

If the `version` property is not set and the  `--build-name` and `--build-number` options are not provided, the build command will not change the `local.properties` / `Generated.xcconfig` file.

This reverts commit 0f557e72.

Dart is migrating to .dart_tool/ as the location for cached artifacts
and other temporary files generated by tooling in the SDK. As part of
this, pub will be migrating from .pub to .dart_tool/pub.

In future, this path will also be used for other tooling, such as package:build.

* update the IntelliJ metedata templates

These URLs all automatically redirect HTTP to HTTPS so makes sense to point users at the secure versions.
