Voting % should not go to 0

[dotmacro]

Problem

During group creation, the user can select "0" as the voting percentage.

However, because "there should always be at least 2 yes votes" (which is correct and good), the 0% threshold will never be honored. (By contrast, it's possible for 2 "yes" votes to be >1% of a group.)

Solution

Change lower value to 1, so slider goes from 1-100.
