Save base layouts

[Gambrinus]

really need the ability to save multiple different and partial base layouts. i like to work on my base design while troops are building in my queues, but often times getting the perfect base layout take a lot of time. so i have the option to either spend time in map editor while my troops are waiting for me or give up on the new design and send my troops into battle. (the latter is the one that i do most of the time)
