Resolving bug #82, changing `paste` command to `paste0` to remove `sep=''`.
Added the `.Deprecated` tag to `get_contacts`.
Added flag to indicate get_contacts is deprecated in the help description.  Changed the example for `get_contact` to remove mention of `get_contacts`.
Put the old plural functions back in and added deprecation.  Cleared out the help functions for them too.  Increased the version to 1.0-1.
Merge pull request #89 from SimonGoring/master

Reinstated the plurals as deprecated functions.
