Replaced global variables by a new hydro_space struct that is part of space. This struct is then passed on to hydro_init_part, and used to initialize the Voronoi cells. For non SHADOWFAX_SPH schemes, this struct is empty. Replaced random_uniform declarations in some unit tests with the tools.h version. Added some more comments to 3D Voronoi code; it is now almost completely documented (meaning I almost completely understand it now).

Cleaned up Gizmo fixes. Added a hydro_timestep_extra method and added an empty version for all hydro schemes.

Check whether particles or cells are active via an inlined function rather than via a direct read of engine->ti_current

Replaced all calls to fminf and fmaxf by the macros that was added for the integer min/max functions.

First initalisation of particles now happens in space_init() and not in engine_init_particles() any more.

Changed 'c' and 'POrho2' to 'soundspeed' and 'P_over_rho2'. Fixed signal velocity assigment bug in vectorised versions of the force interactions.
