[Explorer] Make internal links open in the same tab - external links …

…in another one (#1029)

# Summary

Closes #1020 

Added `_self` to internal links to open same tab.
Added `_blank` to external links to open another tab.

# To Test
1. Open a page with links. i.e : `address/0xb6bad41ae76a11d10f7b0e664c5007b908bc77c9`
     * Click on a Token link or address next to the `User Details` title. Those links will be opened in another tab.
     * Click on an order link in the table. Those links will be opened in the same tab.
