Updates for locales check and some rework on:

Locales: Entirely in "try" block, shouldn't fail at all
Help: changed brackets so () is mandatory and [] is optional
Bans: Added description to help how to ban by name
Bookmarks: changed /del_poi and /set_poi to /poi_del and /poi_set to be
more consistent
Warp: Changed /move_ship to /warp_ship to be more consistent with /warp
for players

Version update to: 1.3.1
