Support searching account name, too

[kgrossjo]

I have multiple email accounts, and the most common use for switching folders is to switch to the corresponding inbox folder. But I have not found a way to include the account name in the search string.

I even made my account names really short (E, G, S, X are the shortest ones) and I was hoping to be able to enter something like g/i or g inb or inb g or inb/g to go to the inbox folder of the G account.

I have nine accounts and so the current way to go is to enter something like inb and then hit cursor down the right number of times (which will be a different number of times each time).
