support programs

There is also a need for extra support programs in ProWesS. Since the beginning, ProWesS relies on some (readable) files which control the loading of programs (most importantly the "mine_personal_ldr" file), and files which indicate what has to be displayed in the menu buttons ("_mbt" files). It would be useful to have some simple support programs which allow you to delete groups of lines from the personal_ldr file, or allow you to add actions (most importantly, definitions of global variables and new buttons). Another useful support program would allow the creation and modification of the files which control the menu buttons.
