5.8.2beta16

Mbm_route2mission: Change so that no edgetech behaviors are output to the mission script
if no sidescan or subbottom is enabled.

Format MBF_MBPRONAV (165): code changed so that if a file has records in which the date
fields (yyyy mm dd hh mm ss.ssssss) are all zero, then on reading the data will be set
using the value in the time_d (epoch time in seconds) field.

Mbauvloglist: Fixed bug that caused occasional crashes.

Mbphotogrammetry: Now applies CLAHE equalization to images before calculating disparity map.

Libtrnav (src/mbtrnav/): Many fixes by Kent Headley, including casting the code to use
Proj for geodetic transformations when used as part of MB-System while still allowing
use of the old GCTP library when used in other contexts lacking Proj.
