tutorials: reactingTwoPhaseEulerFoam: Updates to steamInjection

Added limiters for the phase temperatures to prevent divergence, and
monitors to report the minimum and maximum values. Removed the
setTimeStep functionObject as the temperature limiters make this
unnecessary. Dereased the number of energy correctors and set a higher
Courant number limit to reduce the execution-time of the case.

Patch contributed by Juho Peltola, VTT.
