Use builtin SWIG conversions for glib types

Browse Source 
Where possible in the Python SWIG code use the builtin SWIG conversion
code over custom code. This ensures appropriate overflow/type checking.
With this I have enabled GncNumeric from longs and tested for correct
overflow handling.

Note: This could be extended to GUILE but I am not familiar enought to
safely enable this.
