V1.61 Push Swap

Now working to sort a list with:

• from 2 until 7 numbers, in a optimized method
• more than 7 numbers, without the best sorting method

Bugs just fixed:

• Now the program accepts a large negative numbers list #18
• Now the program blocks if the is a non number at the list #20
• Now the program blocks unexpected signs (-) and (--)
