Initial commit for ALF-10419:
- Bulk Filesystem Importer - Adapted from work by Peter Monks (see http://code.google.com/p/alfresco-bulk-filesystem-import) and Romain Guinot - Refactored to limit repeated code - Refactored to use the Bulk Processor - Currently limited to one bulk import at a time (enforced by lock service) - Unit tests added - Some fixes applied - Performance tests; tried different filesystem "walking" strategies - Still to do: yui dependencies - are these necessary? git-svn-id: https://svn.alfresco.com/repos/alfresco-enterprise/alfresco/HEAD/root@31100 c4b6b30b-aa2e-2d43-bbcb-ca4b014f7261
