More bonus content for Level 3 and above supporters (Patreon)

For quite a long time, I have been neglecting bonuses for Level 3 and above supporters. So from now on, I have decided to provide more bonus content for them. I will publish pre-release/testing build and additional content more often (each 1-2 weeks). Most of this content will be present in the next release, but level 3 supporters will have the ability to review and test it sooner, in more condensed form. 

In will not in any way delay planned monthly releases of new versions.
