add version selecting, and other minor change (#2207)

- Splits Seedminer into 2 pages, using includes. Prevents people from clicking on the twn method if they don't have a taiwanese console
- Adds a new version of Soundhax, for cart-updated consoles, more include, troubleshooting should stay

Make version selectable

This happens in order (with if/else statements):
- People select other -> redirect to checking for cfw(Checking for cfw might have to be reworded, redirecting people to NH if they boot into the HOME menu with Sys/Emu yah)
- People select 11.3 or lower -> redirect to standard Soundhax
- People select 11.4 or higher but nver < 37 and System version isnt 11.16(universal-otherapp patch lol) -> new fancy Soundhax-sp page, adds instructions on what to choose in the what you need section
- Function is called to check if cver combined with nver is sslothable... feedback appreciated on the numbers etc
- People select T as region -> redirect to seedminer(twn)
- People select C as region -> Display message pointing at ntrboot
- If none of the things apply -> redirect to Seedminer
