Version 1.2.0.1 - New version schema and typo corrections

I recently learned how version numbering can work, so I virtually moved versions 1.0.0.1 and 1.0.0.2 to 1.1 and 1.2 respectively, and this one has a few typos fixed so we increment the last one:

For anyone curious, this is my first attempt at structuring this!

a.b.c.d

a: major story addition or major new feature

b: new feature or minor story addition

c: bug fixes, fixes of unintended behaviors

d: typos, visual adjustments
