Incorrectly strips ., p and y from end of module name

[jonseymour]

The intent of the referenced line of code is to strip the extension .py (and only the extension .py) from the end of the filename to yield the module name.

raw-sql-migrate/raw_sql_migrate/helpers.py

Line 73 in 3ff3e80

migration_module_name = name.strip('.py')

However the actual effect of the referenced line of code is to strip any occurrence of '.y', 'p' or '.' from the end of the file name irrespective of whether the characters occur strictly in the context of the sequence '.py'

To reproduce, attempt to create a migration whose name ends with the letter 'y'.

The problem is that the python strip() function does not have the intended semantics of stripping a suffix, only individual matching characters.

It should also be noted, that the point this statement executed, name did not actually contain any .py suffix.
