Added reserve and append functions to FloatArray.
Added "padding" argument to DofManager::giveUnknownVector in order to make implementation easier for XFEM and other code that might need it.
Added computeVectorOfVelocities and computeVectorOfPressures to FMElement.
Replaced EquationID argument with the more flexible dofidmask for computeVectorOf***.
Replaced equation id by dofid array in some function calls.
Added default implementation for giveElementDofIDMask
Remove superfluous EquationID from ActiveBC functions.
Fixed error in stokesflowvelocity homogenization.
Merge + removal of redundant function EIPrimaryUnknownMI_givePrimaryUnknownVectorDofID which already exists as giveElementDofIDMask.
Removed EquationID.
