Package.getActivationCommands is deprecated.

Use `activationCommands` instead of `activationEvents` in your package.json
Commands should be grouped by selector as follows:

``` json
"activationCommands": {
"atom-workspace": ["foo:bar", "foo:baz"],
"atom-text-editor": ["foo:quux"]
}
```

```
Package.getActivationCommands (/Applications/Atom.app/Contents/Resources/app.asar/src/package.js:808:9)
Package.hasActivationCommands (/Applications/Atom.app/Contents/Resources/app.asar/src/package.js:733:20)
(/Applications/Atom.app/Contents/Resources/app.asar/src/package.js:185:24)
Package.measure (/Applications/Atom.app/Contents/Resources/app.asar/src/package.js:163:15)
Package.load (/Applications/Atom.app/Contents/Resources/app.asar/src/package.js:177:12)
PackageManager.loadPackage (/Applications/Atom.app/Contents/Resources/app.asar/src/package-manager.js:355:14)
```

Start by inspecting package.json and locating the activationEvents declaration referenced in the issue. Replace it with the shown activationCommands grouping, then load the Atom package and confirm the deprecation warning no longer appears.
