Change the way we automatically update version numbers

[finnagin]

From discussion in #67 and #66 @uhbrar and myself thought it might make sense to change the code that automatically bumps the version number to increment the patch number instead of the minor number. I.E. an automatic version bump would be like 1.2.0 -> 1.2.1 instead of 1.2.0 -> 1.3.0. Then, we would just update minor/major numbers manually when we feel it is appropriate.

Does anyone have any thoughts or reservations about making this change?

Seems sensible to me.

Yep, I think it sounds fine as well.
