This issue is not always reproducible but when it does occur it happens
somewhat consistently on both 32bit and 64bit builds(Tested on Windows 7).
The midiOutReset call does not return (or it takes so long that it might as
well be indefinite) and as it is not strictly necessary just remove it.

Add functions for get/set the Multimedia timer resolution, although we are
really only interested in the minimum, this will facilitate testing
Put timer utility functions inside nested namespaces as they are platform
specific
