[tahoe-dev] zsh completer

[eurekafag]

What about zsh (and possibly other shells) completer for tahoe paths?
Would be a great feature I think. For now I should remember or list
paths to use command line utility, that's not quite usable. Imagine if
you can type <<tahoe put ~/to<TAB=>>do.txt
tahoe:<TAB=>wall_of_text>wo<TAB=>>rk/do<TAB=>>cuments/<RET>>> Hope you got
the main idea. Often it's just not an option to mount the entire tree
via sshfs, so such a completer will serve for good.
