Fixed handling of inventory in creative mode (normal inventory is not trashed anymore), fixed mese pick speed, added some forgotten stuff

Added message of the day and made it properly configurable using /#setting (not saved to config file yet)

Made picking items up in creative mode delete them (because they usually are in the inventory already anyway)

Lowered default viewing range minimum to such that it allows fairly good framerate in jungles with sucky hardware.
Almost all computers stick to the minimum with the current farmesh range that someone has set up without asking from me, but farmesh is not used as default anyway so those that use it can raise the lower limit in their configuration as they wish.
