Moved many of the boinc specific wxWidgets configuration issues out of config.h

and into a separate file in m4.  Modified the configuration to use the default
wxWidgets configuration if no wx configurations options are found.
Configuration will now succeed on a debug build if the wxWidgets debug libraries
are not installed.
