(svn r11474) -Feature: Allow to resize on creation the smallmap gui in order to show all the types industry available.
-Feature: Allow to enable/disable individually or all at once, the industries shown on small map.
This will permit to easily find those that are of some interest for the player.
Heavily based on gule's patch
