Dont include dot-files in the Docker images

[bschmalhofer]

Local .* files are not meant for the Docker images.
Exceptions to that rule are .bash_aliases and .bash_completion. Check the Dockerfiles.

According to https://docs.docker.com/engine/reference/builder/#dockerignore-file excludes can be declared in the .dockerignore file. There is no minimum version mentionened. So we can ignore all dot-files with the exception of the files that are currently present in the image.

root@f3fe825a0a0c:/opt/otobo_install/otobo_next# ls -lda .*
drwxr-xr-x 1 otobo otobo 4096 Apr 21 17:44 .
drwxr-xr-x 1 root  root  4096 Apr 21 17:44 ..
-rw-r--r-- 1 otobo otobo   21 Apr 21 17:44 .bash_aliases
-rw-rw---- 1 otobo otobo 1453 Apr 21 16:52 .bash_completion
-rw-rw---- 1 otobo otobo 1604 Apr 21 16:52 .fetchmailrc.dist
-rw-rw---- 1 otobo otobo 2181 Apr 21 16:52 .mailfilter.dist
-rw-rw---- 1 otobo otobo 2478 Apr 21 16:52 .procmailrc.dist
-rw-rw---- 1 otobo otobo 1097 Apr 21 16:52 .screenrc
-rwxr-xr-x 1 otobo otobo  298 Apr 21 17:44 .vimrc

Exceptions to the exeptions are .bashrc and .vimrc which are created in a step of the Dockerfile.

Toplevel .* files are now ignored. Testsuite still looks fine. Closing this issue.
