Auto display the information of the address

Add an option that automatically displays the information of the address(es) present on the web page. This avoid clicking/hovering.

Steps for code:

1. On page load, perform a single request to blockchain (or other provider) with all addresses (possibly limited to a fixed maximum, say 100 or whatever max specified in their API).
2. Display the info for all addresses.
3. Additionally, allow to hide the info by clicking on the icon.

Replace blockexplorer.com by a different provider.

Blockexplorer is not returning results for BTC anymore.

Dynamically generated HTML is not parsed

The extension only parses the initially received HTML, not any HTML that is later dynamically received e.g. by AJAX calls.

Reproducible examples:

1. Bitcoin address on this page is not parsed
   https://chrome.google.com/webstore/detail/bitcoin-sneak-peek/nmoioahfkdpfpjngcljhcphglbdppdmj
2. Visit https://github.com/steven2358/BitcoinSneakPeek and the click the readme.md link. The Bitcoin address is not parsed. Though reloading the page triggers a correct parse.

Extension text copies out

To recreate, copy text which contains the sneak peak button and paste.

show tags in address info

in order to get additional information on the address
https://blockchain.info/tags

Issues when trying to contribute

I know how to listen on the DOM and therefore fix issue #2, but when loading the src locally I get Uncaught TypeError: Cannot read property 'nodeType' of nullwalk @ content_script.js:17.

Can you help me figure this out so that we can contribute to the extension as a community?

Cheers

Tooltip instead of injecting text directly.

It would be great to have the balance/etc... in form of a tooltip/popup instead of injecting the balance text directly. Ideally (maybe with an option in the settings) it would automatically pop up when hovering over the icon.
