Add whatis_filter option to filter eligible map locations for travel

Browse Source 
Compound option whatis_filter, filters the eligible map locations
when getting a cursor location for targeting. Accepts 'n' (none),
'v' (map locations in view), or 'a' (map locations in the same area,
eg. room or corridor).
