Implements a phase distrortion limiter which is supposed to improve stability. The limiter value is currently hard code to an arbitrary value: limVis = 0.0000001;

fix an issue with initialization  of beta and kappa parameters in MultiphaseTwoPhaseFieldsPressureFilterLBMKernel after restarting, need global refactoring kernel parameters

Pressure filter and pressure gradient computed so that boundary conditions can be used. Everything is limited to a single block.

Velocity formulation with filtered pressure and handmade periodic boundary conditions. WORKS ONLY WITH ONE BLOCK! No other boundary conditions.

Velocity fomulation without viscosity correction and no output for pressure and wrong output for velocity

Classical rescaling of phase field distribution to 1/3 rho as common in Lee-literature. The source terms were removed from the moments and returned to the distributions based on the original code of Safari.

fix the issue in FullVectorConnector derived classes: add initialization function of base class in derived classes

MultiphaseVelocityBCAlgorithm::applyBC(): vleocity in phase field taken from getBoundaryVelocityX1(). There is still something wrong as the actual velocity in the simulation is much higher than set in the input file!
