Add update folder

Hello,

I have a suggestion to add for BungeeCord: a plugin update folder.

Spigot & Bukkit both have an plugin update folder located at /plugins/update in which you can drop plugins, and after a reload/restart those files are moved to the plugin folder. I'd suggest the same for BungeeCord, since it's:
a) Handy, you can drop updates and just wait till the next Proxy restart.
b) Just a.

I never know when I restart my Proxy next, but I sometimes have updates for plugins ready which I most likely...
