Subject: [PATCH] Fix race-condition with multiple workers

When running ssg with multiple workers, different forked processes might check
for an existing folder and attempt to create it "simultaneously",
which will cause makeDirectory to fail (folder already exists) and ssg to abort.

The fix uses 'force' to ignore errors on makeDirectory(). If it fails with errors
other than 'folder already exists', then the following put() should also fail,
meaning, it won't go unnoticed.
