disable auto-backtrace for C++ unit tests, try to get stderr again

We have some problems where the test executable is not generating
all the right output on travis, it seems not to be getting stdout
or stderr or something. The test executable was being run through
gdb at all times, with commands to backtrace on case of crash.

I'm not sure if gdb is eating the output or what, but for now I
am disabling the feature in the hopes to get the error messages
again.
Merge branch 'master' of https://github.com/wesnoth/wesnoth

add "render-image" CL option, to directly save output from IPF's

Example usage:
wesnoth --render-image "units/undead-skeletal/banebow-bow-attack-1.png~SCALE(144,144)" "banebow.bmp"
Merge branch 'render_imagepath'

UtBS S9: Don't let Esanoo speak a line clearly not intended for him
Fixed dehydration not working on embellished desert
Fixed duplicate unit id's by PLACE_UNITS_RANDOMLY
Fixed issues in MOBILIZE_SIDE

The unit re-creation method caused things like HP mismatch due to the
original unit having traits but not the re-created. It was also
needlessly verbose when a simple store/unstore does the job.
