*** Global variables ***

Other than the user, room and region structures there are quite a few other
globals. I won't mention all of them here but I'll mention the important ones.
The purpose of most of them can be gleaned from just looking in globals.h.

char *command[] - array that stores the command words.

int com_level[] - stores the level of user than can run the equivalent command
   in the command array.

char text[ARR_SIZE] - general purpose array used for output.

char word[MAX_WORDS][WORD_LEN] - contains input words from user on command line.

int word_count - count of the number of words in the users input (1 - n)

char inp_objstr1[ARR_SIZE],inp_objstr2[ARR_SIZE] - the names of objects found
   in the users input by the find_sent_objects() function. inp_objstr1 is
   the subject , inp_objstr2 is the object.

char join_word[WORD_LEN] - "to", "in", "into" or "from" found in user input.

int this_room, this_region - these are set to the room or region function
   number being called when said function is called.

time_t boot_time,reset_time - time mud was last booted/reset.
