changed limiter to enum class to fix adjoint species bug (#1550)

* changed limiter to enum class
* changed ENUM_LIMITER to LIMITER. also changed implementation of turbulence boundary conditions: limiting the implementation of uniform inlet bc to the actual inlets
* fix use of SetGlobalParam for species in fluid iteration
