Both L2-misfits are now normalized at each iteration. Therefore, both objective functions should be weighted equally.

This fix will reset the conjugate gradient history each time a frequency or workflow stage is switched. If such a stage is switched we will have a "new" objective function, thus, it makes no sense to use the old gradients for speeding up the convergence. This bug was the reason why the objective function could not be reduced for 2-3 iterations after a new frequency stage was appplied.

I switched the naming of the variables of the frequency filtering to a more clear and easy one. The change affects the JSON input file and the code itself. The following renaming is used: FC_START -> F_LOW_PASS_START FC_END -> F_LOW_PASS_END FC_INCR -> F_LOW_PASS_INCR FC_EXT -> F_LOW_PASS_EXT FC -> F_LOW_PASS F_HP -> F_HIGH_PASS However, old JSON files will also work for now. If one of the old variables is not found, IFOS will search for the corresponding old one. This option will be removed in a future release.

In case of the SH waves, the STF wavelet was NOT used. To calculate the synthetic data, a new synthetic wavelet was calculated.

When L-BFGS is used and no Wolfe step length could be found, the L-BFGS needs either be resetted or the algorithm has to switch to the next workflow line. This fix will let the algorithm switch to the next workflow line without a model update.

The STF wavelet was not filtered with the frequency filter. Therefore, the residuals were calculated between the unfiltered synthetic and the filtered observed seismograms.

Implemented an offset based tracekill for STF. Makefile in par folder has now two new targets: 1. make install, do an install from precompiled files 2. make reinstall, do a clean install

(1.) Renamed function err() to declare_error(). This was a problem, as many standard libraries also has functions err(). (2) I fixed a lot of compiler warnings like unused variables and uninitialised variables. However, here is a lot of work to do.
