Add license column to softwares, normalise footnotes
I was browsing the repo and upon reading the software files I wished it was specified whether a software was open or closed source, so I added a column that specified this alongside whether it is paid, in an "AlternativeTo" style. As I was doing this, I found it prudent to add some clarification in the form of footnotes and having read the readme.md, I believed the current implementation of footnotes gathered on the one file was clunky markdown-wise (even if it was nice for the user) and didn't use github's markdown footnote syntax, so I normalised all of the footnotes using proper github markdown syntax at the cost of added redundancy. I also slightly reworded some footnotes to better suit their new context. I removed some that were redundant, namely the 1.17.x compatibility ones. May have missed something but I'm pretty sure I got everything.
I believe that is everything I did in words now, please DO make edits, comments and everything else, that is what GitHub is for!
The rating is there for new people to modded so they can pick a launcher while overwolf is quite the bloat its better for a newbie as its easy to make a modpack or just download one, MultiMC is great for someone who just want max performance and full control
Why not note that MultiMC will give you max performance and full console while over wolf is more intuitive for new people but is bloated and so on for each
