Mapper improvement - can now be zoomed

There is an enhancement to the mapper module (which will be released with version 4.71).

If you want to get it in advance, download from:

https://github.com/nickgammon/mushclient/blob/master/lua/mapper.lua

(RH click on "raw" link and save the resulting file on top of the mapper.lua file in the MUSHclient "lua" subdirectory).

The improvements let you use the scroll-wheel on your mouse to zoom the map in and out.

Modifications to add manual resizing and redoing the configuration window to properly float so that it doesn't have to hide options to fit. Also added zoom in/out hotspots to config. Ported over from my working copy for Aardwolf.
