Italian: Escape an apostrophe.
SyncAdapater: Set supportsUploading to true.

SyncAdapter: doRegularTasks: Catch NoNetworkException in each method instead.

Otherwise we cannot unset in-progress booleans, so we never try again.
ClassifyActivity: requestSync(): Get the account name and pass it.

Passing null instead works, but it is undocumented so it seems unwise to
depend on it.
LoginActivity, LoginUtils: Call setSyncAutomatically for the account.
LoginUtils: Make sure that automatic-sync is always set.
