beesh: added mee_*_pre and mee_*_post calls for every bee_run action..

now you cann add mee_install_post() actions to your bee file which will
be executed after bee_install has been run..

so there is no need to add bee_install calls to mee_install functions just
to create/move/unlink some links/files post installation or pre patch..
