Rename PLIST_UINT to PLIST_INT and add plist_new_int() and plist_get_int_val()

This properly supports getting and setting signed or unsigned integer values.
Also, a new helper function plist_int_val_is_negative() was added to determine if
a given #PLIST_INT node has a negative value or not.

The old type PLIST_UINT is defined as a macro with the value of PLIST_INT for
backwards compatibility.

This commit also adds int vs. uint support to the C++ interface, and the python
bindings in a hopefully useful way.
