wip: Support web3 >= 1.0.0-beta.38

[sunify]

It's a more workaround rather final solution. I think we should extract web3 stuff from core and create a separate package for that. Same for ethers. Otherwise it would be kinda hard to do #82

FYI #66

[sunify]

Yeah, i saw it, thanks. Just don't want to drag all this web3 stuff into our precious library :-)

[troggy]

why package-lock?

[sunify]

Oh, we hadn't it before?

[troggy]

only yarn.lock

[sunify]

Ok, looks like i missed when we started use yarn in this repo :-) Will remove

[troggy]

@types/web3 still uses old Web3, so typedefs of leap-core are not going to work with latest web3 :(

testing it with leapdao/bridge-ui#163

[sunify]

Fuck. Totally forgot about typings :(

[troggy]

if we update typings here, this will break type-compatiblity with older web3, right?

[sunify]

Not sure. Will take a look at typings and what we can do.
