This patch is mostly to add a permission node for the new sleep rewards feature. The permission is 'smoothsleep.sleepreward', and is granted by default (hopefully).

I've also tweaked a few really minor things. Removed some debug output lines and such, so hopefully less spam for people who like keeping debug on. I've also set the default value of the notify on login option to false since it can be annoying, especially if I keep finding reasons to release small patches.

tl;dr - There are no bug fixes or such in this version vs 2.5.0, so don't feel compelled to update, just minor tweaks and a permission for sleep rewards.
