Added an object to put the retrieved data in.

Hi,

  We have an svn project that is using multiple external dependencies.  When using svninfo i noticed that it always put the retrieved data into svninfo. This caused us to have to store the data between calls.

  I have modified the module to accept a name of an object to put the information into. This way I can create an object per retrieval and then look up the information i need per object.

  I submit this for your review to be added to the project.
