project設定の修正＆ContextScopedProviderの追加
Pass the application as parameter to module constructors

As Roboguice does.
This allows modules to access application-contexted resources when
necessary.

Note that Roboguice looks for a constructor taking a Context (not
an Application), but since we got the Application we can be more
specific here.
