Add a Feature Support BitArray to the IOLayer

This way we know what an IOLayer supports
Adjust IOSerial and MyPty to that change

Fix the after close window the previous session
window is empty bug
in Mainwindow::remove we had a problem
first we removed the currentSession from the tab and then
deleted the session
The problem is that removePage on OTabWidget does signal currentChanged
so we did not delete the session intended but the wrong one
because m_curSession got adjusted after a removePage...

3rd fix the close and reopen bug in MyPty

+Ok we all know we write perfect code
+but sometimes the compiler produces bad code
+and we need to work around some compiler bugs!! -zecke
+
+MyPty is broken in some ways
+ if you do connect/disconnect/connect sh will be executed in the
+ process of opie-console.... funny aye?
+ 
+OTabWidget seems to give us problems too
