Introduce drawing styles, adding a line style in addition to the
existing points.
Settings are style={points,lines}, default is now lines.

No idea why this was in there. Though it makes the leader jump
by huge values, since it still winds up as samples on the same
path, just non-continuous, the swarm still appears correct,
hiding this braino.
If you reduce the SWARM_SIZE to a tiny number like 2 though, it
becomes very obvious that the leader is teleporting all over the
place.

Originally the thinking was that rototiller modules would become
dlopen()ed shared objects, and that it would make sense to let
them be licensed differently.
At this time only some modules I have written were gplv3, Phil's
modules are all gplv2, and I'm not inclined to pivot towards a
dlopen model.
So this commit drops the license field from til_module_t,
relicenses my v3 code to v2, and adds a gplv2 LICENSE file to the
source root dir. As of now rototiller+libtil and all its modules
are simply gplv2, and anything linking in libtil must use a gplv2
compatible license - the expectation is that you just use gplv2.

Largely mechanical rename of librototiller -> libtil, but
introducing a til_ prefix to all librototiller (now libtil)
functions and types where a rototiller prefix was absent.
This is just a step towards a more libized librototiller, and til
is just a nicer to type/read prefix than rototiller_.

Just a fun little swarm based loosely on 80s-era boids
It would be interesting to make stuff like the # of particles
and the weights runtime configurable, or exposed as knobs.
Using a Z-buffer for occlusions and perhaps shading by depth might
make a significant improvement on the visual quality. It might also
be interesting to draw the particles as lines connecting their current
position with their previous, instead as pixels. Or fat pixels like
stars...
