Fixes to `buck quickstart` so the project builds in IntelliJ out of the box.

Summary:
This almost makes thing work, though I am still having a problem with debug.keystore.
I posted a question on StackOverflow, which hopefully one of their devrel people will answer:

Test Plan: Run `buck quickstart`, import the project into IntelliJ, and try running "Make Project".

+  This is the default AndroidManifest.xml used by Android library projects in
+  IntelliJ, as such projects need only the package attribute in order to
+  decide which Java package to use for the generated R.java file.
+
+  Because we use "com.facebook" as the package for all of our R.java files,
+  we can share the same AndroidManifest.xml for all of our our library projects.
+  This helps keep the /java/ directory clear of cruft.
