Add better support for sessions

[bckp]

What?
As of now, sessions kind of work, but it is really unstable and perform log-outs time to time, with session reset, mainly on Process reload, we need to find another way to deal with sessions that will be safe to use in long running process, to enahnce even more the RR with Nette, with this we you can use RR as primary server even for Session required projects
