Add support for vendor customisations in install script

Currently apt repos are hardcoded to come from upstream ubuntu
and the github account is hardcoded to stackforge. In order to
support alternative distributions using this data model, this
patch adds a variable called $vendor that can customise these
according to a particular distributor's preference.

+### Using a vendor modification
+
+You can specify a vendor, which will change both the apt repository and the git repository the data defining the deployment is drawn from. Currently the only option is cisco, which can be set by:
+
+    export vendor=cisco

 ###Additional information on the data model being leveraged is available in the data directory of this repository.
