induced current, constant space, etc. Not finished
fix in space_constant, progress on magnetic.xml
total current added to xml
is bool progress
changes after rebase to  new master. magnetic.xml has been altered to value3 and value4 (induced currents) from scratch due to many conflicts (using the new master), so it may contain errors. Calculation, however, seems to work.
forms progress
minor module changes
checkbox supported in material dialog
qui progress
gui fix
changes in module, new comsol test for fixed current. Now fails external/induced current density
magnetic harmonic module changed to fit comsol values
more quantities tested
rebased to latest version of agros/master. Does not work, would not save the special L2 Const space
test work as it did previously. Problems:
1) some quantities are still wrong
2) saving of ConstSpace and solution has to be implemented in Hermes
