Official Launch of Dappkit

DEV-287-wallet-connect-integration (#20)

* allow a web3Provider to be used on the web3connectionoptions

* add some tutorials on how to use the custom web3 provider (still needs testing tho)

* make sure that web3CustomProvider is not a string

* remove "connect" if provider is connected, because we already started and account is already loaded because the provider should be the one taking care of that (userland)

* change markdown

* add how to walletconnect to how-to readme.md

* unused and web3link variables

* lint

* comment out two lines after the "enable" warning

* remove web3 and add taikai/dappkit as dependency
