Allow player to apply for a job

[matthew-parlette]

After #27 is done, we need to have a system for having the player apply for a job. For now, as soon as the player applies for the job, they should get the job.

@cparlette: I'm having trouble with 79a362f14596b88698edc551f9cb4b323f7adc17 to try to sort the list of jobs to apply for by the rank of the job.

I'm trying to handle the sorting of the Menu.options in the JobMenu class, since it is specific only to that menu.

To reproduce:

1. N for new game
2. A to add player
3. S to start game
4. M to move
5. B for bank
6. A to apply for job

The list should be (when it is working properly):

t. Teller m. Manager (Enter to cancel)

Any reason not to use the job.rank instead of the job.symbol, as in 8911dd14c90d576d1b1052cb671a1914be75e79d ? I know it's not exactly what you were going for, and I don't know if it has other repercussions, but it sorts the list right.

Perfect solution, thanks for the help
