Made gettext work on most OSs. Tested on Debian, FreeBSD, Gentoo, and Windows.

Added a search path option to the Config script for cmake to use when finding libraries for modules or for gettext.
Fixed m_mysql and m_ssl to work under Windows, made the Windows Config
program remember the last used options, and fixed Windows release builds.
