Working version with 2 local dirs

If you try this, you should definitely change the paths to the local
directories of the storages in the hoarders_srv.xml. The option for
users to select directories will be added soon.
Initial commit to this branch

- Added basic syncing with multiple directories
- Directories specified in the hoarders_srv.xml
- Added progress bar whilst files are being copied
- for now, new subdirs are created instead of subdirs being copied from
the original dir
- made some changes to xml structure of hoarders_srv.cml
Files and dirs copies over now retail meta-information

This commit isn't the most thoroughly tested. Also, this doesn't work
for empty directories.
Fixed bug of empty sub-dirs not getting copied

Cleanup, refractoring, and empty subdirs not getting copied over. This
commit should close out this branch.
