Added first version of the new backward tracking method. It is now possible to use interpolation methods as well.

Bugfix, Plotting the soundsource line segments used a wrong algorithm to estimate the already processed combinations.

The soundsource combination panel now shows the segment color as background if the "Update track parameter" is enabled in trajectory output.

The offsets get recalculated.

Integrated the empiric_offset and empiric_drift parameter of the float, Changed copy offsets layout.

The measured soundspeed is now being updated on applying a status to temperature and pressure, as well as on loading an rfb file.

Bugfix, if the zoomed area does not contain any topographical lines, it will now produce a warning instead of an error.

The etopo file must be downloaded separately and linked as parameter
etopo in the files section in artoa.ini file.

The user now gets notified when there are points selected that do not match the lifetime of a soundsource.

The restore view button has been implemented in a custom function for temperature, pressure and toa window.

Pick point and polygon methods are now equal to time of arrival in pressure and temperature windows.
