svn 587 - session conflict on double login

[Florianer]

Hi,

I made a subdomain http://svn.mycka.de/ to login to RoundCube instead of All-Inkl.com-Webmailer. Now I like to login into more than one account at the same time. Opening a net tap in Firefox, same address, other email account. This results in a login error. I thought, I made a mistake on my password, tried again... the same. If I now logout the first account, I am not able to login again. It seems to be related to the database session table. If I clear it by hand, I can login again. <= Logout will not clean the session in database.

This are now 2 requests in one post:
1) The request to bug fix this.
2) The request to make it possible to login into multiple email accounts from one URL at the same time.
