Closes #32 (closed)
This MR removes duplicates in
check.sh, therefore hindering one image to be built multiple times from the same commit.
It also fixes something that could have been a future issue. If e.g. the directory
cc7-cms would have a sub directory in it and a changed was pushed to that sub directory, then the old script would fail to build the
cc7-cms image. The fix of looping over
dir_wo_duplicates instead of file paths fixes that.
