Use libcurl instead of hacky HTTP download code

[vgmoose]

In Utils.cpp, on Switch targets, libcurl isn't able to be used. This results in slower, unreliable http download code.

There's a libcurl portlib available on dkp-pacman, but using it results in the following compilation error:

/opt/devkitpro/portlibs/switch/lib/libcurl.a(libcurl_la-mime.o): In function curl_mime_filedata':
mime.c:(.text+0x1a50): undefined reference toaccess'
/opt/devkitpro/portlibs/switch/lib/libcurl.a(libcurl_la-timeval.o): In function Curl_now':
timeval.c:(.text+0x10): undefined reference toclock_gettime'
collect2: error: ld returned 1 exit status

What's your problem exactly? Removed the -DNOCURL flag, added -lcurl, and all builds flawlessly and works fine.

You're right! It used to be crashing my Switch (after resolving the above mentioned build problems) but with the latest libcurl package everything looks good.

Removed NOCURL code from fortheusers/libget@2338da5
Updated progress bar to use curl's progress callback: 023373a
