Description of Change

ZWave requires number to sent as signed integers when using Configuration:Set otherwise the lua library throws an error when the last bit in the integer is used and number if not negative

Summary of Completed Tests

Tested with devices with a Configuration parameter of size 2 and a configuration value of 43200
When using an unsigned integer the lua library would throw an integer overflow error at runtime, fixed when converted to signed integer
