First step to make lyx2lyx code support both python 2 and python 3 (3.3+)

Browse Source 
Most of the changes are related with dictionaries returning views instead of
lists.

xrange -> range (since xrange is gone in python 3)

The code that is special to support both python 2 and 3 is enclosed in a comment
 \# Provide support for both python 2 and 3
and
 \# End of code to support for both python 2 and 3

And so later it can be removed safely when python 2 is no longer supported.
