Jordan/344 block explorer

[jbibla]

• could use some advice on how to set up search for all blocks instead of just blocks since subscribing to tendermint event for NewBlock...

• not sure if the meta info from implement block explorer main page #344 is available? does anyone know?

• working on tests now

closes #344

The meta info isn't available. If we want it (which would be pretty cool to have), I think we have to store the data locally in a file or a database and then query that for the historical info. Of course we won't have data for when the UI is closed, but I think it's an acceptable compromise for a client-only block explorer -- like the Activity Monitor on macOS or Task Manager for Windows.

I think tracking this while the app is open could be enough. I want to mention my concerns for introducing additional complexity by adding a database.

[jbibla]

ok. i think we should merge this then.

• there is already a separate ticket for tests unit tests for blockchain components in /monitor #121
• meta info would be cool but we need to discuss a strategy for this
• http://explorer.cosmosvalidators.com/#/ ???

[faboweb]

We aligned on including tests for all changed or created components per PR. ;P (sorry for being annoying)
Moving meta info out is ok. Could you maybe create a ticket for that?

[nylira]

I'll help with block search right now.

Not sure why this test is failing:

 FAIL  test/unit/specs/components/monitor/PageBlocks.spec.js
  ● PageBlocks › should show the search on click

    TypeError: Cannot read property 'filters' of undefined

Everything else is working well though. Good job @jolesbi, it's going to be useful.
