reworked phase field interface to damask spectral solvers. now specify 'thermal a b c' or 'fracture a b c' to activate either phase field where a b c are the initial value, diffusion coefficient and mobility respectively. 

Right now only thermal and fracture phase fields implemented and only in the basic petsc solver
