Possible assignment/comparison bug

[dschmidt]

Hey @jangoclik

my compiler complains about some AI code that looks possibly wrong:

[ 19%] Building CXX object src/CMakeFiles/c4.dir/Players/AiPlayerGood.cpp.o
/home/domme/dev/sources/c4/src/Players/AiPlayerGood.cpp:413:31: warning: equality comparison result unused [-Wunused-comparison]
                    tempPlayer==field[row-1][column+1];
                    ~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~
/home/domme/dev/sources/c4/src/Players/AiPlayerGood.cpp:413:31: note: use '=' to turn this equality comparison into an assignment
                    tempPlayer==field[row-1][column+1];
                              ^~
                              =
1 warning generated.

Please fix :-)
