Some customers upgraded ZK from < 8.5.0 to 8.5.0, the first incompatible thing is the new default Iceblue theme bigger padding/margin. This makes them headache because the layout needs to be re-tweaked.

So in 8.6.0, we'll release a new theme based on Iceblue, but the padding/margin is tuned to be nearly compatible with old default Breeze-like theme. This will be also applied to ZK Theme Pack.

for example: iceblue -> iceblue-c (c stands for compact)

On the other hand, all iceblue-like themes will have a compact clone.
