Faster account switch

One nice feature I've seen in Tusky (Android Mastodon client) is the ability of open a post/tool as a different account. It's a 3 taps experience (menu, open as, select which account).

Doing the same with phanpy requires more operations:
1. Select toot
2. Click toot menu
3. Copy url
4. Go back to "home" ?
5. Click to menu
6. Accounts
7. Switch to new account
8. Click to menu
9. Search
10. Paste url

It would be nice to add a menu item to use at step 3 above to directly "open as another user"
