search endpoint (#161)

Implements a search endpoint
* For a numeric value, tries to fetch a block
* For a hash value (length 66 with 0x) tries to fetch a block, a transaction and logs by signature. Whichever returns data first will be returned
* For a hash value (length 10) fetches transactions with that function selector
* For addresses, uses RPC to check for code. If not configured, looks at latest transactions and determines if it's a contract or not. 
For EOAs returns last 20 initiated transactions
For contracts returns last 20 received transactions
