Adding support for 0.21 or more clear documentation for 0.19

[cevatbostancioglu]

Hello, toolbox repo cannot be built with 0.21, because of some structural changes in bitcoin-core. instead of master branch, i have tried to use 2f9f9b37b595c409bbd7282aa41b28478c79b574 commit for bitcoin. but i can't compile bitcoin-core with qt5/qt4 and i dont understand why toolbox links bitcoinqt binary/library. makefiles are old? So, what is your suggestion to me ? i want to use this tool by the way, i can start to porting toolbox repo to 0.21 ? also ninja build is not working.

this is everything i have done so far

#!/bin/bash

cd bitcoin
#git checkout 2f9f9b37b595c409bbd7282aa41b28478c79b574
#git pull
