Add Explorer nav link to all pages when explorer is enabled

Dynamically inject an Explorer link into the navigation on every page
when currency_info.explorer_enabled is true. Links to the external
explorer URL (e.g., voidbind.com:9090).

Pages updated: dashboard, graphs, stratum, miners, miner, index, share.
All pages now have consistent navigation:
  Dashboard | [PPLNS | Sharechain] | Graphs | Stratum | Miners | Classic | Explorer
