Feature/network status

[kkx]

related to showing block number tested with local geth, worked. with https://giveth.psdev.io:8545/" the eth.isSyncing is not responding, so it is "synced"

Is should be responding with false like this:

$ curl -X POST -H "Content-Type: application/json" -d '[{"jsonrpc":"2.0","method":"eth_syncing","params":[],"id":1}]' https://giveth.psdev.io:8545

[{"jsonrpc":"2.0","result":false,"id":1}]

[kkx]

this should work, change to getSyncing since this method exists in both environment

I like it, should do some more styling but I think it serves the purpose for now :).
