- bugfix reset routine
	- split status reports into smaller chunks, callable by other parts
	- control bits now reports not only the pure data, 
		but also the meaning of the single bits
	- changed show representation of some "boolean" like variables

+ cosmetics

check
	- uartSplitUartString:
		- now with argument, to also split other strings
		- removed maximum length check
		- return value on error is -1 
			- (before 0, could interfere with correct but empty result)
		- corrected remainder filling, current result was missing
		
	- introduced max length command check into ISR, 
	  setting a flag, being checked in Process_Uart_Event 
	  
	- some additional refactoring of names 
	- some doubled PSTR replacements by one common static string   

spiApiShowBufferContent
	- added spiApiShowBuffer
	- in addition moved max/min definitions to api_define.h

value...
	- removed all byteCompletion fcn and calls
	- changed return values to uint8_t returning spiApiCommandResult_XXXX 
		- spiApiPurgeAndFillWriteArray
		- spiApiAddToWriteArray
		- spiApiAddNumericParameterToByteArray
		- spiApiAddNumericStringToByteArray
	- refactored 
		- spiApiFillWriteArray to spiApiPurgeAndFillWriteArray
		- spi(Api)AddNumericParameterToByteArray
		- spi(Api)AddNumericStringToByteArray	
	- introduced spiApiCommandResult_UNDEFINDED

FALSE/TRUE   
	cosmetics

	- refactored CHIP_MAXIMUM to CHIPSELECT_MAXIMUM
	- added eclipse specific #ifndef __AVR_AT90CAN128__ statement
	- added CommunicationError statements

apiShowOrAssignParameterToValue 
	- created spiApiInit 
		called once at the beginning or on reset
	- names refactored several times, q.v spiApi.h
		spiApiCommandResult_SUCCESS...
	- apiShowOrSetValue/apiShowOrAssignParameterToValue
		- refactored to: apiShowOrAssignParameterToValue
		- arguments changed in a more general way to also allow to choose:
			- parameterIndex, message string
			- ptr_uartStruct not needed
		- reduced core part to call of two new functions:
			- apiShowValue
			- apiAssignParameterToValue
	- spiApiSubCommandCsPins
		- implemented showing of configuration
		- missing: to new fcn to add/remove		

if there is not enough space in the readbuffer the write functions will return dez 20. Florian Brabetz
