update released cross-cutting oasp modules

[maybeec]

We already have a bower repository for our oasp modules: oasp/oasp4js-bower
However, for resolving the typescript migration in #80, we first should use our oasp modules like any other application will do. Thus, we can ignore the migration of the modules for now and suspend it to a later point in time.

Furthermore, please consider the discussion in #91.
@mmatczak:

1. is there any documentation how to release the modules in the bower repository?
2. do we have to change anything to make the modules also available for npm?

Currently, I am blocked working on #80 as I would have to upgrade all cross-cutting libraries to continue. I would not recommend this for now, due to additional work. More important is the fact, that the sample application should not build the modules, but the sample application should use the modules!

The current release-task does not work as of the following issue.
I already tried to upgrade minify-css and del dependencies due to my google results, but unfortunately the problem persists....
