"Delete Account" in a very unintuitive position

[mark-orion]

Reproduce issue:

• be a newbie on ChatSecure who wants to delete an account (In my case the non-working GoogleTalk account as Google does not support XMPP anymore).
• fiddle with the UI and do not find anything useful where you would expect it.

The current place of the option to delete an account is not intuitive. I had to ask in the forum to find this out. I suggest to put it into the main account preferences page right under "Display Your Fingerprint" - this is where I expected it to be.
