Renamed SDN-IP packages and classes.

The code use to use the name 'BgpRoute' in a number of places, which is not
descriptive and doesn't map to how we talk about SDN-IP (we always call it
SDN-IP in all other documents/presentations).

Details of changes are as follows:

net.onrc.onos.apps.bgproute -> net.onrc.onos.apps.sdnip
    BgpRoute.java -> SdnIp.java
    IBgpRouteService.java -> ISdnIpService.java

created new package for web classes: net.onrc.onos.apps.sdnip.web
    BgpRouteResource.java -> IncomingRequestResource.java
    BgpRouteResourceSynch.java -> OutgoingRequestResource.java
    BgpRouteWebRoutable.java -> SdnIpWebRoutable.java
