Improve 2012/konno/try.sh

Now randomly selects 10 numbers (in range $((RANDOM % 101))).

Also allows one to pass in numbers (or if they wish to they can pass in
non-numbers) to pass to the program.

The script has new fun numbers.

Removed that the valid range is from 0 - 255 as numbers bigger than 255
not only work but some show some fun output (a number of which are used
in the script now).

 ## Try:
 
 ```sh
 ./try.sh
+
+# you can also specify numbers to try before the random and preselected ones:
+./try.sh 111 222 333 444 555 666 777 888 999
 ```
 
+Try running [try.sh](try.sh) a number of times as the first part randomly
+selects ten numbers to try.
