Added confurable # of times

* Added generic function to get a integer value.
* Increased the number of strings asked for to three. Soon rand will
pick which one to combine with a random number, then write it to
seed.file in order to seed vanitygen

* Overall performance will be slower as vanity gen has to be called and
reseeded each iteration.
* Have not checked the getNumber() function for errors when int not
given.
