fixed using namespace issues:
never include the whole std namespace! always include only exlicit types
f.e. using std::cout; or using std::string;
- first implementation of telnet commands
- added new "printf" style Trace macro with debug zone support

ToDo:
- refactor telnet functions
- implement all missing  telnet functions
- implement telnet testcases
- improved TraceBuffer() macro to support hex and other outputs
- moved TelnetResponse to own file
- beautify Telnetresponse.cpp
- harmonize Trace() and TraceBuffer() macro
refactored telnet code
refactored TelnetRecv
complete default telnet values
- for a stable telnet connection, we have to read the command prompt (<2.31>) too. The bad thing is, the prompt is version depended, so right now it is only working with wlan firmware v2.31.
ToDo: implement a unittest based on this strict implementation, than we can work on a more flexible solution.
implemented unittest for ComProxy::TelnetRecv()
- fixed bug in ComProxy::TelneRecv()
implemented ComProxy::TelnetSend unittest
hardend ComProxy::TelnetSend unittest
implemented ComProxy::TelnetOpen unittest
- implemented ComProxy::TelnetClose() with save/dont save option
- implemented unittest for ComProxy::TelnetClose()
implemented basic unittest for WiflyCOntrol::ConfSetDefaults()
refactored WiflyControl::ConfSetDefaults() unittest
Merge branch 'telnet' into dev

Conflicts:
	WiflyControl.cpp
skip unimplemented unittests
- started implementation of ComProxy::TelnetSendString
- extended FormatGuidlines with static, const and enums
- added debug zone ZONE_VERBOSE for Trace messages which occur to often for ZONE_INFO
implemented ComProxy::TelnetSetReplaceChar
