Refactor typings as necessary. In order for `bignumber.js` in the root
`node_modules` to not conflict with `@types/bignumber.js`, specify
`"bignumber.js": "5.0.0"` in `devDependencies` and `"embark-ui/bignumber.js"`
in `nohoist` of the root `package.json`.
In `packages/plugins/rpc-manager` switch from callback to promise usage with
respect to `web3.eth.accounts.signTransaction` because of a [bug][bug]
discovered in web3 v1.2.4.
In `packages/plugins/solidity-tests` specialize the tsc compiler options with
`"skipLibCheck": true` because of a problematic web3-related typing in the
`.d.ts` files of the remix-tests package.
Bump ganache-cli from 6.4.3 to 6.7.0 (latest) because 6.4.3 doesn't support
`eth_chainId` but web3 1.2.4 makes use of the `eth_chainId` RPC method (EIP
695).
BREAKING CHANGE: bump embark's minimum supported version of parity from
`>=2.0.0` to `>=2.2.1`. This is necessary since web3 1.2.4 makes use of the
`eth_chainId` RPC method (EIP 695) and that parity version is the earliest one
to implement it.

Upgrade all dependencies on web3/web3-* v1.0.0-beta.37 to v1.2.1.
Make various adjustments related to the previous convention of
`"web3": "1.0.0-beta"` in `embark.json` signifying that embark's own web3
dependency should be used in dapp builds.
Fix bugs in library manager, including a switch from using the
live-plugin-manager package to using npm in a child process to install
`"versions"` dependencies specified in `embark.json` when a specified version
doesn't match up with embark's own version for that package.
Avoid race conditions when installing `"versions"` by completing all installs
prior to starting other services. If an install fails, then after all the
installs have completed or failed the embark command will exit with error.
Change various comments and update docs to reflect the new default of web3
v1.2.1.
