added marketmaker_build_depends.cmd script

(git and cmake installed are required)

script will automatically download and build all needed *.lib and *.dll
for build marketmaker.

currently script built only 64-bit Release versions of *.lib and *.dll,
pthread_lib.lib is compiled for statically linked and 	nanomsg.lib and
libcurl.lib for using with dlls: libcurl.dll and nanomsg.dll .

Later i will improve it to build both 32-bit and 64-bit versions, and
versions for static linking marketmaker without any external deps. But
this will take time and some work on MSVC project files (marketmaker.vcxproj
and marketmaker.sln).
