created .gitignore
deleted bwchart/bwchart.suo and included *.suo to gitignore - this file contains developer-specific options
added a define to suppress old string function warnings
made some changes to gitignore to make final release build results downloadable from github
added hsvrgb.cpp and hsvrgb.h to bwrep.vcproj to make it buildable
added "DllExport" attribute to class BWrepActionList to make bwrep buildable - I am not sure that it is right
added define to suppress old str function warnings to bwrep/StdAfx.h too
