The Big Blob update, Part 1

Created by: DeityLink

First part is almost exclusively a graphical revamp, but there are a few exceptions so read on:

• Blobs now emit a cloud of purple smoke over whatever they are affecting. So now you get a clear visual feedback when someone gets attacked by them, or they destroy something (wall or item).
• Huge revamp of the blob's visuals. Blobs now support two kind of looks: classic ones (made from 32x32 dmi) and new ones (made from 64x64 dmi)
• The new looks feature added overlays, animations, such as connections between the blobs, or various feedback animations (normal blob transmitting a pulse, factory producing a mob, resource producing a point, etc)
• The new looks also features a damage overlay, letting you know approximately how much health the blob part has. In the classic look, only the normal blobs have a damaged sprite.
• When a new blob gets created (through game mode, random event, or admin spawning), the overmind player gets to choose the blob's looks.
• Admins can set the looks of every blobs in the world by the push of a new button under the Fun tab.
• Resource blobs now look darker if the overmind they were connected to has died. Other overminds can hover near it to take ownership of them and re-activate them.
• Overminds are now immune to singularities, their pull, and Nar-Sie.
• When a blob gets pulsed, it will now hurt any mob standing on their tile. The "telescience teleporting you right next to the core so you can destroy it without any danger" strategy is now suicide, unless you have a really good armor, a really powerful gun, and even then it will require some testing.

Also a few background changes in the code. Did you know that humans had two blob_act() ?

Also pulses now transmit over time, instead of instantly, which miraculously reduced the CPU cost by a ton. So even with the new stuff, blobs are now much less laggy overall.
