Calling censusPanel.update() with poorly skilled kittens crashes game

Issue #85 resolved
Jesse Allen created an issue

If a kitten has just begun a job, their experience in the job is 'undefined'. When the game panel updates, it yields a TypeError on line 1465 of Village.js.

record.content.innerHTML += "<span title='" + exp.toFixed(2) + "'" + style + ">"

"Cannot read property 'toFixed' of undefined"

I believe the fix here would be to give kittens 0 experience in their jobs when assigned.
