Channel.getNormalUsers() returns duplicated users

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Connect to ix.undernet.org or irc.freenode.com using other IRCClient using 
nick: userA
2. Let this client create any new channel, i.e.: channelA => userA is the owner 
of channelA
3. Pircbotx joins channelA using nick: userB
4. userA parts channelA
5. userA joins back to channelA
6. Pircbotx's ListenerAdapter's onJoin method detects userA joins channelA
7. Do a Channel.getNormalUsers() call in onJoin() method.

What is the expected output? What do you see instead?
Expected: userA, userB( or just userB, either way is fine depending on the 
server's policy)
Instead: @userA, userA, userB

What version of the product are you using? On what operating system?
2.1. But I suspect that 2.0.1 would produce the same bug.

Please provide any additional information below.
Channel.getUsers() and Channel.getNormalUsers() are quite confusing right now. 
I myself would expect:
i) getUsers(): returns all users including privilege annotation prefix. But 
would it be better of just plain users' nicks? Since you have getOwner(), 
getOps()... for that matter already.
ii) getNormalUsers(): returns all users without special privilege.
iii) getUsersNick(): returns the nicks of all users, right now is buggy as well 
(returns: @userA, userA, userB)

If its the servers' issue and Pircbotx's design is fine. Could you provide a 
fix to overcome this?
Thanks.

Sorry, that was from the newly added NAMES parsing which didn't account for 
opped/voiced/etc users that have symbols in their name. Fixed in Revision 
0960b8f186f2

With your last paragraph, I think this bug confused you. getUsersNicks() will 
return just the plain nicks without any symbols. getUsers() has always returned 
the User object so you can get more information.
