Improve and add 2012/endoh1 try scripts

Browse Source 
The new try.sh and try.bw.sh scripts run the program on one file (passed
to the script) in colour and without colour respectively. One file
because one has to terminate the program.

The new try.alt.bw.sh is like try.alt.sh but uses the black and white
(original submitted entry) version.

The scripts for the alt code allow one to set the different variables
that can be redefined. The use is the same variable names as in the
Makefile. For instance:

   TIMER=5 SLEEP=5000 GRAVITY=I VISCOSITY=4 PRESSURE=1 ./try.alt.sh
   TIMER=5 SLEEP=5000 GRAVITY=I VISCOSITY=4 PRESSURE=1 ./try.bw.alt.sh

for the gravity 'I' and:

   TIMER=5 SLEEP=5000 GRAVITY=N VISCOSITY=4 PRESSURE=1 ./try.alt.sh
   TIMER=5 SLEEP=5000 GRAVITY=N VISCOSITY=4 PRESSURE=1 ./try.bw.alt.sh

where 'N' is some number. Obviously the other values can have different
values than given above. Some of these values are protected against in
code (to an extent - if the user wants to set them to strings that's on
them) but not all are and the scripts do not try and check for the user
either.

The endoh1.alt.c file was changed in that one can now define SLEEP (S in
the code) to 0 like the original, should they want to see the original
but with other values specified. That will make it flash much more
quickly which can be a problem of course but that's up to each user.

There are two alt versions that let you control the compile time variables that
control the fluid behaviour and the added variables to speed up or slow down the
fluid as well as setting a timeout (if not 0): one for the original black and
white and the colour one added by the author at the request of the judges.
Another version is the deobfuscated version provided by the author as well. See

If however you wish to change the gravity factor, pressure factor and/or

There is no restriction on what the number is because doing so prevents the
macros from being defined to `I` which would prevent the author's remarks about
it from being done.

Try slowing down the display by increasing the sleep time from `12321` to
`50000`:
The `SLEEP` variable is to delay the time between updates to make it easier to
see and to not flash too quickly. The code protects against a value < 0 and
defaults to 12321 but you can change it to. For instance to slow it down you
could increase the sleep time from `12321` to `50000`:
