Modify buffer limit to 4kB.
Merge remote-tracking branch 'github/testing' into testing
raised buffer limit in IRCConnection (for text recieved from irc-server)

from 1KB to 4KB. To reduce possibility of long messages messing with the
processing chain in the read() main loop.
Now Problems only occur if 1(!) irc message is longer than about 4096 chars.
