Exchange Branding / Switching. Allowing exchange prefix filtering.

Here's a thought. Make the exchange selectable in the top left.

Clicking the Exchange name here would give an information box with some links and settings available maybe, you'd like to set an exchange skin here to further distinguish it.

The ">" would pull out a drop down to select which exchange you wanted.

The default would be "ALL Exchanges" and would not filter the prefixes. Maybe call it BitShares Core or something better than All exchanges.

On the Markets list give a *info marker that states the prefix has been removed. In this photo i also show what it might look like dropping the BIT prefix from core smartcoins USDb CNYb etc.

No files, tests, or entry points are named. Review the supplied screenshots and the existing top-left exchange label and Markets list to determine the scope of exchange selection, prefix filtering, informational links/settings, and prefix indicators; done would require an agreed design and working behavior for these interactions.
