[Urwid] Escape sequences

On my Ubuntu install I need to install a separate package to get the 
terminfo for your terminal.  So, if you ssh to a system like this then 
Urwid apps won't support your F-keys.

In addition to querying the terminfo we could add your conflicting 
escape sequences to a list to check *after* the default ones fail, that 
way there might be a slight delay in recognising your keys but at least 
they will work.

My thinking is that the wide range of interesting terminals are fading 
away and that supporting the ones people are still using without 
requiring properly configured TERM and terminfo would be great.
