TRENT: Add box for specifying unused numbers
A suggestion: Add a box to allow to specify a comma-separated list of unused numbers. These numbers will simply be skipped during random generation.
For example, if you run a contest with 10 numbers. 8 entrants enter and number 8 and 6 remain unused.
Then you could specify 1-10. and then "6,8" as unused numbers.
The random generation could technically work like an 1-8 lottery, but if any number higher than 5 is chosen (in the above example), then 1 is added to the random output, and if the resulting number (even if no 1 was added) is higher than 7, add 1 again. (in the 7 case, 1 is added because its higher than 5, which puts it higher than 7, which causes 1 to be added again). Basically, the translation table would be: 1->1 2->2 3->3 4->4 5->5 6->7 7->9 8->10
