#73 Multiple codes to ignore with pylint

Currently you can only ignore one error/warning code
with this syntax "#IGNORE:DXXXX".
I sugegst to allow multiple things like this
"#IGNORE:DXXXX FYYYY ..." and also allow wildcards in
the numbers, for example "IGNORE:W?" will ignore all
warnings.
This will be very useful since ATM you can´t suppress
all spurious warnings when e.g. working with PyQT
