ASCII Bill Invaders V0.G6 - new skin!

Today, or rather, tonight, I fixed the 64 colour enemies firing so that the battery acid drops in between the enemies. This makes it easier to avoid clashing with the enemy graphics, and pasting a copy of the enemy graphics onto the acid path as it drops.

Copied the new enemy fire routine to the second and third enemy fire timers, for levels 2 and 3, and switched those on. (not sure if these were enabled in the demo??)

Fixed a bug where the mat behind the enemies was pasting the mat in the wrong places.

Added graphics to mother ship.

Added a skin to the display, to show what this might look like. Not sure what to do about the white text around the frame. Maybe I could use a different colour, or removing the frame some more? The frame is split up into 4 parts - left, right, top and bottom, so I can move or remove various parts of it. This opens the door to various other skins too??

First experiments tonight show the acid leaks over my new skin frame. This is actually a mystery why it does this, but I quit like it in a way. The Bill ship (head) also needs to be figured out, but with the skin frame placed lower and higher, the effect is rubbish. Maybe it doesnt need a top and bottom frame during the game??
