Improve page titles for SEO

[Hugoo]

We are missing on SEO by using the same very basic title for each pages.

Change titles to:

• [page name] - Walletbeat to Ethereum Hardware Wallets [page name] - Walletbeat for pages under: https://wallet.page/hww
• [page name] - Walletbeat to Ethereum Wallets [page name] - Walletbeat for pages under: https://wallet.page/wallet/summary

Sounds good to me.
