src/m_zeeman.cc: Now takes manual angles given the right GIN. Useful with
Oliver's named argument implementation to make simplistic magnetic field 
calculations without having to recompile the code or having to specifically
customize the magnetic field.

* src/methods.cc: manual_zeeman_angles_on, manual_zeeman_theta and
manual_zeeman_eta are added as GIN to abs_mat_per_speciesAddZeeman.
The first is a tag that will set eta and theta to the other two accordingly.

	* controlfiles/testdata/chevallierl91_all_extract.xml: 
	  included information of the sourde of these profiles.

	* arts-2-1-524

	* CMakeLists.txt: Introduced a target check-xmldata (which does exactly
	that - executing the arts-xml-data tests) and adapted make check setup
	such that xmldata tests are NOT executed with this one.

	* controlfiles/CMakeLists.txt:
	Introduced further tests, particular xmldata tests.

	* controlfiles/artscomponents/helpers/TestForloop.arts, TestHSE.arts,
	TestRegridding.arts, TestAgendaCopy.arts:
	Added. Tests of some ARTS helper methods.

	* controlfiles/artscomponents/arts-xml-data/TestIsoRatios.arts,
	TestSpectro*.arts, spectrotest.py:
	Added. Tests of toolbox spectroscopic and isotopologue ratio data.
	CAUTION: TestSpectro*.arts require HITRAN data, hence are not included
	in the make check target. Also, they need quite a bit of runtime.
	Nevertheless, they are part of the ESA planetary toolbox test cases,
	hence we want to have them in the repository.

	* controlfiles/artscomponents/ppath/TestRefractPlanets.arts:
	Added. Testing MWgeneral refraction method.

	* controlfiles/artscomponents/arts-xml-data/TestAtmScen*.arts,
	TestAtmScenSup*.arts, TestSurf*.arts:
	Minor modifications.

	* AUTHORS: Added myself.

	* src/methods.cc: Spellfix.

	* controlfiles/planetary_toolbox/validation/common/spectroscopy/
	SpecCat_Consistency_Perrin-vs-HITRAN.arts:
	Corrected f_grid setup.

	* doc/uguide/absorption_theory.tex: Minor layout fix.

	* controlfiles/artscomponents/arts-xml-data/TestAtmScen_Mars.arts,
	TestAtmScenSup_Mars.arts:
	Bugfix (get data from arts-xml-data, not from Jana's homedir!).

	* controlfiles/artscomponents/arts-xml-data/TestSurf_Mars.arts:
	Removed leftover Print calls.
