Mixed line endings cause problems when exporting patches with
git-format-patch and then trying to "git am" a patch with mixed and
non-matching line endings. In such a situation git will fail to apply
the patch.
This commit runs the dos2unix tools on the remaining files with CRLF
(\r\n) line endings to convert them to line-feeds (\n) only.
Files that are Windows specific like *.vcxproj and *.props files were
not converted.
Closes: #3073
* all lock/unlock and unlock/lock pairs are done by RAII guards now
* fixed two possible crashes at the end of battle when last stack was killed by spell. That should fix#749 and #752.
* fixed a very nasty race condition, eliminating possible deadlock at the start of battle when human hero has tactics
* fixed#422
