(Feature) Unlimited amount of custom RPC endpoints

[vbaranov]

Relates to #26

Unlimited numbers of custom RPCs can be added.
Networks dropdown was updated to support vertical scroll.

I think we should display a visible scroll bar, it will help on the user experience

[vbaranov]

@patitonar I was trying to visualize scrollbar before submitting a PR. And decided not to include visualization, because of some visual artefacts at dropdown opening/closing animation. I would suggest adding visualization in a separate PR.

@vbaranov
If network is LOCALHOST then
Settings->Current RPC field is empty

or custom rpc name displayed if there is custom rpc has been added

yes, it works in such way from the beginning. Could you please create a separate issue for that?

I didn't catch this one. Could you clarify?

@fvictorio could you take a look to this PR? do you have any concerns?

[fvictorio]

Yes, sorry. This looks good. My only comment is that I think the new RPCs should be at the end of the list. Now the list shows the newest first (after Localhost 8545). But this is something that can be done in a separate PR.

It makes sense, especially for the big list of custom RPCs and while we have no ability to hide the list of custom RPCs. I added this fix to PR. Thank you.
