-------------------

updates deps.md (freebsd had a package that didnt exist, oops)
netbsd also had outdated packages

moved windows caveats into the user guide (because well, those are user stuff, not build caveats)

MANY redundant wording removals (especially on dynarmic)

proper capitalization of Eden, Dynarmic, Amiibo, and CLion

fixed discord link on metainfo as well
also fixed file associations as well otherwise installed eden wont have icon over NSP/XCI/etc files

"please" is filler

fixes a HANDFUL of dead links as well
