Create Home page

The next page to recreate is the Home page. Right now unfortunately it uses data from hive blog. I'm going to copy some mechanics from previous version of gui here with the new structure, to have everything ready for API change.

For far we have had:

1. Head block data on the left.
2. Last transactions for that block (currently not working because of wrong number).
3. Link to Witnesses page

I'm going to remove point 3. and remake the rest.
