Moved include rtl_tcp.h from rtl-sdr.h to rtl_tcp.c (where it should be)

*	So @f4exb was right to include the rtl_tcp.h in CMakeLists install. If anyone is making a C program that communicates with rtl_tcp, it will probably use the enums. (See PR keenerd#22 and issue keenerd#21)
*	Added rtl_tcp.h to CMakeLists install script and moved rtl_tcp.h include to rtl_tcp.c file
*	Added Eclipse gitignore (for anyone that uses eclipse to compile)
*	Closes Issue keenerd#21
