#1 double qoutes removal from imput files

[Matej ZaGiBa]

It's common practise export CSV files with strings delimited by " and escaped inside strings by another "

String qouting is especially important when dealing with strings like phone numbers which should not be converted to float.

Attached patch against 0.4.2 changes one line of csv2xls.py so doubleqoutes are removed on import.

In future single qoutes string delimiter should be also considered.
