Delay setting the /cset CHANMODE mode on new channels until the channel is synched.

Instead of setting the mode at NAMES time (when we know that the channel is new),
remember this for later by setting the GOTNEW flag in the joinlist entry.  Then
check this flag when the channel is synched.

Setting the channel mode takes us out of server "grace mode", which slows down the 
processing of subsequent commands and drastically reduces the number of commands we
can have outstanding before we get kicked off for flooding.  This change allows us
to stay in grace mode while we're synching every channel that we joined at connect.

In turn, this makes joining lots of channels on connect faster, and much less likely
to cause us to be booted with "Excess Flood".
