* a.m32: new state 'correctslopes' which will check all ceilings and floors for a stat&2 and heinum mismatch and correct accordingly (the result isn't visible, but such an inconsistency can prevent planes from TROR-joining)
* helper feature: when shade preview is enabled, the ceilings and floors of highlighted sectors are shown in pal 6. This makes it possible to highlight the TROR-joining candidate sectors in 3D mode using e.g. 'sethighlightsector searchsector 1' while aiming at the respective ceilings and floors, and get visual feedback.
* when failing TROR-joining early ('no consistent joining combinations found'), print to the console why it failed.
* more Makefile.deps updating
