add support for oF 0.9, vs2015

turboJPEG libraries for vs2015 compiled straight off the sources using the following recipe:

+ download turbojpeg release:

	http://sourceforge.net/projects/libjpeg-turbo/files/1.4.1/libjpeg-turbo-1.4.1-vc.exe/download

+ download nasm (net assembler):

	http://www.nasm.us/pub/nasm/releasebuilds/2.11.08/win32/nasm-2.11.08-installer.exe

+ copy nasm.exe into the cmake/bin directory so it ends up in the PATH for the cmd prompt.

+ use cmake-gui and cmake to build visual studio project files, compile turbojpeg

+ find turbojpeg-static.lib and it's debug counterpart.

+ rename the debug .lib to turbojpeg-staticd.lib (note the 'd' for last character)

+ copy both lib files into the lib folder in the ofxTurboJpeg addon.
