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

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netbsd also had outdated packages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

-Modern game consoles require heavy power to be emulated appropriatedly. This is why the emulator uses an approach known as HLE (High-Level-Emulation), in a nuthsell: Instead of accurately emulating every subsystem that forms part of a component, emulate the resulting visible I/O interface instead.
+Modern game consoles require heavy power to be emulated appropriately. This is why the emulator uses an approach known as HLE (High-Level-Emulation), in a nutshell: Instead of accurately emulating every subsystem that forms part of a component, emulate the resulting visible I/O interface instead.
 
 For example, take a disk write, instead of emulating a proper SD card we instead use the C++ standard library for I/O. Additionally we use the abstractions provided by the `fs` service to "lie" to programs about certain SD card properties. Notably this includes making up sizes for the fake SD card, giving "realistic" values or expected outputs for a given card, and so on. And instead of writing to an actual SD card, the emulator simply writes to a file.
