Added catches for the grabs.

I had an error box in Awesome so I added catches. I hope it is enough.
Fixing tab context menu?
Minor fixes.....
Mostly working on send history

I made it act exactly (afaik) like weechats, because it's simple and logical

Also added some new IRC codes

Added the preferences for maxSendHistory and maxScrollback

Re-did the key bindings for the input since apparently the extra newline
comes from it being a 'text' control, not the Return key press

Edited REC:Etc so that NOTICE's won't ping the user

Added handling the beginnng "NOTICE AUTH" message
