Update the object cache/properties only when action is successful.

 Previously some object properties were being set before the event
 (change label/purge), and if that event threw an exception for some reason,
 the object would have a incorrect value, or not be present in the cache.
Fix and some reworking so that Tuque leaves no temp files behind.

As taken from GitHub, flattenDocument() returns a data structure where the values are blank.  See Islandora-Dev message https://groups.google.com/d/topic/islandora-dev/A_ajiI6stnA/discussion for details.

Add check for writing temp files.

If $this->cookieFile = tempnam(sys_get_temp_dir(), 'curlcookie'); fails,
the problem isn't seen until saveCookiesToSession() when
$this->cookieFile is a boolean null instead of a file name.  This
adds a check to createCookieFile() to make sure the cookie file
in the temporary directory can be created.

Fixed FoxmlDocument not respecting versioning

FoxmlDocument wasn't correcly setting the versioning
flag on datastreams. This was causing any object created
in Tuque using FoxmlDocument to have its datastreams set
to non-versionable.

The fix was a simple error serializing the output of a
boolean to XML. PHP was outputting 1 or 0 for true or
false, while the foxml was expecting true or false. Any
other value was interperated as false.
