Poloniex convenience modifications

[Njall]

a convenience modification fitting onto Poloniex trading page

to install, you have to fit these requirements:

• install Greasemonkey or something similar suiting your platform
• read the code, cut&paste into a desktop file like poloniex.user.js
  (it is NOT advised to blindly install stuff like that since it can do literally anything to your trading portfolio)
• click your browser on that, and enjoy
• tip the author

Update: using icons next to usernames to add/remove them on the list

[Njall]

but what does it do? what are its features

trollbox filter is nice

mostly that. adding buttons next to people names, storing inside a cookie who made it on the lesser noisy trolls list. I mute people.
a feature often requested from the website, but never arrived. now done client-side.
(no update today, need more testing using this myself)
Update works like a charm   storing names inside PoloPreferences cookie.

second is VIP list, and looking for where to store data. On the long, a cookie is small space of some 4Kb. Perhaps I should transform names into numbers using a hash function, and use that for comparison. Or at least clipping to first 12 chars.
