The only description of a chat command was its usage string, which is
meant to be read by a human. A user interface which wants to offer the
commands to a player needs the parts separately: the command, what it
does, and one entry per parameter.
Add ChatCommandInfo and ChatCommandParameterInfo, built from the
metadata which is already there - ChatCommandHelpAttribute for the
command and its required character status, ArgumentAttribute for the
short names and whether a parameter is required, ValidValuesAttribute
for the accepted values. Name and description come from the display
attribute, so they are returned in the language of the player.
The description which is passed to ChatCommandHelpAttribute was never
stored anywhere. Keep it as a fallback for commands which have no
display attribute, instead of discarding it.
The reset info command had its texts hard coded in English. It now
refers to resources like every other chat command does.
