Feature - Implemented pull all command

[IronTetsubo]

I added a "pull all" command, I got tired of having to go to hagnks for this. The "can't pull because you're in ronin" logic isn't tested because... I'm not in that state. This of course is why I noticed the previous "pull" stacktrace...

builds against latest r11411.

I don't know why I didn't do this before, since I regularly go and click that button. I changed the check in your patch to see whether you can pull everything. 11413.

Yeah, easy fix. Cool, re: the changes - I figured checking for -1 budgeted pulls was sufficient, but totally makes sense to be more direct on the validation.
