Create builder for LabsLink

LabsLink works like PubMed but the linkout files are structured
differently
Fetches Dryad Data packages that already have PMIDs associated
Builder uses xom to generate xml
Add titles to DataPackage
Use real title from DataPackage
Add Target for Profile file
Add script to generate LabsLink files
Include labslink shell script in build
Add comments to clarify purpose of LabsLinkLinksBuilder
Tweak output dir to avoid collisions
New script for uploading to LabsLink

Still need FTP host and have not tested
include generateUploadLabsLink.sh in build.xml
Add LabsLink FTP host
Merge pull request #7 from datadryad/labslink

Adapt linkout tool to generate LabsLink-compatible files
