Update AppleDoc install instructions

@tomaz tagged a new version of AppleDoc which resolves the issue requiring
the `--HEAD` param to `brew`, and @adamv [pulled in the change](https://github.com/mxcl/homebrew/pull/14693)
to mxcl/homebrew that both updates to the new code and also uses
the [new compile-time template location](https://github.com/tomaz/appledoc/pull/231)
to avoid the second step.

This caused a Bug that lead to Pods with preferred dependencies to be always
installed.

Closes CocoaPods/Specs#464.

Should fix Travis errors.

They are called after the pods have been downloaded but before the targets are
integrated in the Pods.xcodeproj.

closes #486

* master:
  [Gemspec] Depend on Octokit 1.x and bundle update.
  [Dependency] Always copy the podspec of external sources to `Local Podspecs`

Conflicts:
	CHANGELOG.md

closes #490.

This reduces ambiguity and prevents bugs like #489, which was caused by the
Sandbox creating a LocalPods from the spec in the root (if present) and
ignoring the one in Local Pods.

Closes #489.

The caching of LocalPods might need a refactor.

Closes #485

See #485

Closes #484
