Jabber plugin ver. 0.4-SNAPSHOT

This may be my jabber client (Spark) doing the linking when it sees a URL, but I
think we could put the '%20' in for spaces to help create a usable link, in any
case.

Example result from '!status' bot command (notice the space in the project names):

(1:18 PM) hudson: Status of all projects:
example local: last build: 7: SUCCESS: http://localhost:8080/job/example local/7/
gestalt-example-core freestyle: last build: 5: SUCCESS:
http://localhost:8080/job/gestalt-example-core freestyle/5/
sto: last build: 5: SUCCESS: http://localhost:8080/job/sto/5/
