sparkler: add virtual flag to particle_props_t
The burst particle abused a zero mass to circumvent the effects of aging.
Instead use an explicit virtual flag to suppress aging, change busrt_cb
to ignore all virtual particles instead of only its center. Previously
burst_cb would thrust other bursts like any other particle, and this was
incorrect. Now burst centers are always stationary, even when they overlap
other bursts.
