First attempt on drawing maps

Obviously branching because ... blah, does not work yet ...
Now able to print a map in Qt interface \o/
Improving memory management (allocation/free)

Far from perfect yet relying on valgrind, but I will see that later.
Merge branch 'drawing_map'
removing data/mapserver.log

It shall probably not be used by the map
Update README.md
Merge remote-tracking branch 'upstream/master'
