ascii art animator... take two

here's a take two of the ascii art animator, now in optimized for memory & header file format

    /*

    ascii animated video program
    To create an AAV, simply create a text file with the following format
    1 or 0 <---- put at top of the file. How many numbers indicates how many passes. -1  indicates an infinite loop
   


    3 <--- height of current frame
    000   \
    000    |---content of frame (doesn't matter how wide, as long as it's the same hight as specified
    000   /
    1 <--- how long the frame lasts in seconds (can be a decimal value, e.g 0.04 is 1/25th of a second


    just keep on adding sections like this to build it up frame by frame
    enjoy!
    (thanks for the insults and better code from the /prog/ assholes)
