Financial profiles about host-manager

[n8maninger]

I believe Host Manager already supports what you're talking about? If not let me know what it's missing from the current feature set:

1. Go into the Settings dialog and switch your currency to anything but Siacoin.
2. Go to "Configuration" page
3. On all of the price or collateral related settings a "Pin to currency" button should have appeared in the top right corner.
4. Set your price in that currency and hit "Update"

Host manager will automatically readjust your pricing every 5 minutes or so.

Some documentation on the full feature-set of Host Manager is probably needed 😄
