* smob-value.c (make_value, scm_value_new_bool,
scm_value_new_float, scm_value_new_string): Fix
leak/unininitialized memory problem.

* plugin.c (func_scm_apply): Remove. It called scm_c_eval_string
on the contents of the first argument cell. This is a big security
hole.
(plugin_init_general): Don't export spreadsheet function
scm_apply, which used to be bound to func_scm_apply.
