Level Protection Guards for directions [by Colin Hassall]

In the room where you wish to block the players
you will need to add 2 extra descriptions:

"entry_level" the numeric value of the 
minimum level to pass through (e.g. 20).

"exit_dir" the textual exit name (currently
this only supports the standard 6 exits with
Circle).  (e.g. north).

The exit_dir _IS_ case sensitive, so all lower 
case, but I have added the option to use abbrev. 
so 'n' can be used instead of 'north'.

You can have only a single blocked exit in a 
room, perhaps later versions will allow for 
multiple blocks.

Some people _MAY_ argue it's not good to use 
the extra descriptions in the room, but I 
think it has it's benefits, firstly it can be 
edited with OLC (if installed), and therefore 
doesn't require a reboot.

If you use this let me know via email.  I might 
offer some support, but it's far too simple to 
really require it.

If you want to give me credit then WOO HOO! I 
don't really mind, I know from experience snippets 
are rarely credited.
