Makefile : fix cleaning rules

in order to leave the src tree as clean as before a build
+ add rm -f of autogenerated sim_core_config.h & sim_core_decl.h
  in simavr/Makefile
+ add rm *.hex in example/board_*/Makefile
Merge pull request #7 from mali/working

Makefile : fix cleaning rules
Debian : One big package

Builds one package with all included
 - simavr
 - libsimavr
 - include/simavr/*.h and pkgconfig
rm manpage.swp
misc: Update NO_COLOR define switch

The NO_COLOR define switch is a preparation for the Windows version.
Since the standard Windows command prompt is not able to display
ANSI color statements correctly. With this define switch it is
possible to remove any coloring of the output. This will be set
automatically in the MinGW patch.
The color definitions are moved from sim_core.c to sim_core.h since
they are used in other macros as well.

cores: No standard include paths

There are problems with standard includes since the paths are ambiguous
between host and AVR. Using absolute includes does not work for multi-platform
projects.
The solution is to remove all standard includes of the host system for the
core files since there is no reason why a core definition should require
standard includes from the host system. User interaction (status messages)
is the job of the simulator and not the core definitions.

- add CORE_CFLAGS (-nostdinc) to Makefile.common
- remove <stdio.h> from core definition files
- move init message from core definition files to avr_init() in sim_avr.c

mingw:  make simavr compilable with MinGW

- patch makefiles to work with MinGW
- compile to run_avr.exe on windows, otherwise run_avr cannot be started from the normal windows command prompt
- add sim_network.h to encapsulate the network functions of different platforms
    (use winsock2 for Windows network functions)
- make network helper functions static
- force open() to use binary mode (on Windows default is text mode)
- do not change stderr on Windows
- exclude simduino example on Windows
- add MinGW README

MinGW merge, thanks!
misc: Remove outdated README

There's no point in keeping two similar README's around, and README.md
is better maintained.
