Docker mix and match setup

Rewrite of the docker setup. Now uses fig to manage containers and container
linkage. The base is a block based mix and match, which will give you the
possibility to easily test all configurations.

+Docker
+======
+
+TOOLS ARE WRITTEN FOR TESTING AND TO SEE WHAT IT IS!
+
+For this to work you will need the nifty docker tool [fig].
+
+The most simple setup will look like this:
+
+```sh
+./assemble_blocks.sh docker_gogs w_db option_db_mysql
+fig up
+
+```
+
+That's it. You have GoGS running in docker linked to a MySQL docker container.
+
+Now visit http://localhost:3000/ and give details for the admin account an you're up and running.
+
+
+How does it work
+----------------
+
+`./assemble_blocks.sh` will look in `blocks` for subdirectories.
+In the subdirectories there are three relevant files: `Dockerfile`, `config` and `fig`.
+
+`Dockerfile` will be copied to `docker/` (also means last `Dockerfile` wins).
+
+The `config` file contains lines which will in the gogs docker container end up in `$GOGS_PATH/custom/config/app.ini` and by this gogs will be configured.
+Here you can define things like the MySQL server for your database block.
+
+The `fig` file will just be added to `fig.yml`, which is used by fig to manage your containers.
+This inculdes container linking!
+
+Just have a look at them and it will be clear how to write your own blocks.
+
+Just some things
+
+    - all files (`Dockerfile`, `fig` and `config`) are optional
+    - the gogs block should always be the first block
+
+Currently the blocks are designed that, the blocks that start with `docker` pull in the base docker image.
+Then one block starting with `w` defines, what containers should be linked to the gogs container.
+For every option in the `w` block you need to add an `option` container.
+
+Example:
+
+```sh
+./assemble_blocks.sh docker_gogs w_db_cache option_db_mysql option_cache_redis
+```
+
+
+More sophisticated Example
+--------------------------
+
+Her is a more elaborated example
+
+```sh
+./assemble_blocks.sh docker_gogs w_db_cache_session option_db_postgresql option_cache_redis option_session_mysql
+fig up
+```
+
+This will set up four containters and link them proberly. One for each of
+
+    - gogs
+    - database (postgresql)
+    - cache (redis)
+    - session (mysql)
+
+WARNING: This will not work at the Moment! MySQL session is broken!
+
+
+Remark
+------
+
+After you execute `assemble_blocks.sh` you should always trigger `fig build` to inculde the the new init script `init_gogs.sh` in the docker image.
+
+If you want to use another GoGS docker file, but keep everything else the same, you can create a block, e.g. `docker_gogs_custom`, with only a `Dockerfile` and call
+
+```sh
+./assemble_blocks.sh docker_gogs_custom w_db option_database_mysql
+```
+
+This will pull in the `Dockerfile` from `docker_gogs` instead of the one from `docker_gogs`.
+
+`Dockerfile`s for the `master` and `dev` branch are provided as `docker_gogs` and `docker_gogs_dev`
