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

At a new frequency stage, STF was deactivated after the first shot.

If TRKILL_STF_OFFSET or TRKILL_OFFSET is set to 2, the offset based TraceKill will be applied in addition to the TraceKill file.
Therefore, it is possible to exclude with TraceKill file fault receiveres and use an offset based tracekill with the build in feature at the same time.

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.

(1.) IFOS Makefile
Introduce dependencies files, which contain dependencied of each objective file. Therefore, it is possible to allow a more accurate rebuilt of the objective files.
New standard target is IFOS2D. Moreover a new target install is available.

(2.) Contrib
Fixed the problem with the dependencies files if the hole IFOS folder is copied over to a different hardware architecture.
You may now the error by ".d" files.

The readmod functions verify now the dimension of the model file. Therefore IFOS will abort, if the model file is to small or too big.
Moreover, the write_matrix_disk function is used to write the models to disk.

Bevore the FWI loop the observd data was read in and was time filtered. I think this ist not necessary, as the observed data is read in for the calculation of the residuals again.
Therefore, I removed the code to save calculation time.

IFOS is now able to read in input files, that are formatted according the JSON standard. Nevertheless, the old files will work as well.

In addition, I fixed some compiler warnings.

Conflicts:
	src/exchange_par.c
	src/write_par.c

Changed naming convention of individual spatial tapers for gradients, updated to usage with WORKFLOW

Merge STF_SH into development

INVMAT - > FORWARD_ONLY
INVMAT1 - > PARAMETERIZATION

Adding a few gitignore files to smooth the GIT workflow

! IFOS -> IFOS2D !
- New make targes is IFOS2D
- Generated binary is IFOS2D

Adding 2D to IFOS to indicate, that it is our 2D FWI Code.
