- matcher.cpp, survey.cpp: setting the state pointer to null/nullptr in ::shutdown() to prevent errors caused by accidental double-frees - an additional check if the pointer is null already is not necessary as the standard guarantees that nothing happens if delete is called on a nullpointer

- survey.cpp: rename loop variable for more clarity; replace use of parmeter with use of vector.size(), replace nested vector.at calls with direct index access/subscript as it is faster and easier to read
replace the local/automatic mid_level_tiles variable in matcher::match_world_tile with one that is created once during the setup phase (heap).
The dynamic part of the contained (16*16*3 = 768) vectors is being allocated on the heap in both cases - which made the repeated instatiations of the automatic variable so slow/expensive.
Also replace calls to vector<bool>.resize in nested loops with direct assignments to those vectors, which curiously even after a lot of profiling is the fastest way to reset the inorganic vectors - at least on Windows.
- embark-assistant.cpp: Replace 2 local/automatic mid_level_tiles variables with a single dynamic variable created during setup as well; add calls to matcher::setup() and matcher::shutdown()
- matcher.cpp/.h: add state with mid_level_tiles member; add setup and shutdown functions
- survey.cpp: add function reset_mlt_inorganics as replacement for the looped calls to vector::resize as all inorganic vectors are now expected to have the proper size when entering survey::survey_mid_level_tile
- survey.cpp: add function to copy all incursion values from one mid_level_tile_incursion_base instance to another; replace repeated assignments with calls to new function in survey_mid_level_tile
- survey.cpp: replacing repeated nested vector access with a region_map_entry reference in survey_mid_level_tile; made a reference mid_level_tile const to prevent acidental change of values
- defs.h: using mid_level_tile_incursion_base in region_tile_datum to store incursion data of world tile edges
- survey.cpp: commented out "not used" blocks of assignment in survey_mid_level_tile that no longer make sense now
- survey.cpp: removing layer_bottom and layer_top, which are never read, but slow down survey_mid_level_tile significantly because entries are added quite often into the tree map structure
- survey.h: removing now obsolete include for map
