Feature/build

This patch contains changes regarding the build system so that the *nix and Windows systems use the same information (consistency). Some use names routine names have been changed (from .l files with -P option) to reflect the file name that generated the routines, this makes it easier to create a general procedure.
A number of include / header files are files are generated from different file types (html, xml, js), due some limitations of the windows build system the generated file names had to be changed (the extension in the windows build system is only available including the '.' so e.g. the file jquery_fx.js generates now jquery_fx.js.h instead of jquery_fx_js.h)
In the windows version the creation of .cpp files from .l files has been adjusted to correct for the YY_BUF_SIZE problems.
Furthermore on windows (and also used on *nix) some commends have been replaced with python scripts so that on windows only python is need (besides flex and and bison). On *nix also perl is required for the generation using tmake.

Below a short description of the changes will be given and grouped.

Changed files
=============
- .gitignore
added some directories and file

- Doxyfile
corrected for changed file names

- Makefile.in
added realclean and some other changes (ignore error) and the moment when the Makefile is deleted (as last file).
Added entries for doxyapp and doxmlparser

Added realclean for the following files (consistency):
======================================================

- addon/doxysearch/doxysearch.pro.in
no visible change just spacing?

changed INCREASEBUF script to a python script
changed teh geneartion of some include file, now by means of a pythons script. Names of the generated include file had to be changed as well.
added possibility to generate version.cpp here as well.

Added HEADERS to dependency so non existing but later generated include files are recognized as well:
=====================================================================================================

The file:
=========
- addon/doxywizard/config.l
is replaced by:
- addon/doxywizard/config_doxyw.l
so there are in the system not 2 different config.l files. Renamed some routines from configYY -> config_doxywYY...

New files:
==========
- src/increasebuffer.py
increase YY_BUF_SIZE and YY_READ_BUF_SIZE from 16k / 8k to 256k.

- src/settings.py
create settings.h file

- src/to_c_cmd.py
create include files from different files (html, xml, js) so they can be included in the code as defaults

- src/version.py
create version.cpp file based on the configure file

- winbuild/Config.rules
rules file to convert the config.xml file into configoptions.cpp (doxygen) or configdoc.cpp (doxywizard). Seen the differences 2 rules are created within this file.

- winbuild/Gen_head.rules
rules files to generate include files from different files using to_c_cmd.py

- winbuild/Settings.rules
rules file for generating the settings.h file. It is possible to select to use CLANG and SqlLite3

- winbuild/Version.rules
rules file to be able to start version.py

The files:
==========
- version.bat
- runbison.bat
- increasebuffer.pl
are not used anymore.

I've only added the files as indicated, I didn't remove the files from the repository.
