- Bug fixes in adjoint model

Fix GFED2 Emissions

Fixed an error when using GFED2 8Daily and 3Hr emissions, the error occurred when running backwards because the emissions were called twice.

See Benchmarks results v34 tests 003 and 004

M Undefined

M Undefined on line 1199 of tagged_co_adj_mod.f, this only affects tagged_co emissions inversions.

Error compiling on ifort 12

Fixed an error that made imposible to compile sciabr_co_obs_mod.f on ifort 12. The error was caused by an openmp pragma. This error is entirely a problem of the compiler and not the code itself, this should me resolved on version 13 of the compiler. Meanwhile we just commented the pragma to avoid problems.
