WIP: Integration of IH Cantabria wave modelling contributions

New code

New wave generation model:

• streamFunction: based on Fenton's Fourier approximation

New interFoam-based solver:

• interPorousFoam: alternative method to include porosity effects, to be used with new fvOptions (see below)

New fvOptions:

• multiphasePorositySource: porosity for multiphase flows
• mangrovesSource: mangrove interaction, i.e. drag and turbulence contributions for k-epsilon based models

Test cases:

• interPorousFoam/porousDamBreak
• interPorousFoam/mangroves
