developer_vector_unify: make the const and attr methods work

Neither wrangle compiled: const was missing a semicolon and appended to
an array it never declared, attr used variables before declaring them
and declared bias twice. Both also read parms from an older layout
(falloff, uni_sample_size, bias_sample_size, bias_falloff,
bias_multi_attr). They are rewritten around the basic method's local
average: const pulls it toward the Bias constant, attr toward the local
average of the Bias attribute within Radius with Bias Dist Effect as
its falloff, both scaled by the Bias Multiplier attribute. The
misspelled biasm_ulti_attr parm is renamed bias_multi_attr.
