- modified patch #4681, for scons compiling

of the fluidsim can now be disabled with the
	flag: BF_NO_ELBEEM='true', e.g. for irix systems.
	(The number of ifdefs from the original
	patch was reduced, and the defines are now
	only necessary when elbeem is switched off.)
- particle generation option is available again
