Backward compatiblity to 4.2 for conditionalLoader files

[timomayer]

Moving from bower to npm made a lot of problems since we often reference to dependencies with the conditional loader like "resources/bower_components/*" this files all got a 404 error since the reference was broken an in most projects it is not possible to easily update the data-resource attributes.

Many of our projects are not yet moved to 4.2 so we have a lot of projects where we have to be aware of this issue and find solutions.

Additionally we have to check if we have more of this incompatibilities (we can not solve without backend vendors) with 5.0 and find workarounds.

I added an config object to manually define bower resources needed for backwards compatibility.
See config.js

Dependencies will need to be included via npm, but can be configured to match the old bower_components structure.

hey @alxbenz thanks :) i thought about that issue a lillte bit more. what do you think about a backward compat rewrite in the conditional loader? when the conditional loader detects a url like resources/bower_components/ it rewrites that path to js/vendor ?
would be a smart solution but since we manually define what to copy to vendor i guess we wont have the exact same file namings in js/vendor as we had in bower_resources

we could integrate an easy text checker task to the build sequence that searches for "/bower_components" over the whole project and throws an error in case it finds something. That would result in a broken build and prevents us from delivering broken code. what do you think? @alxbenz @timomayer

But sometimes we do not have the data-resource attr in the framework repo for example ro*** where all the stories using it are in an separate repo

[janrembold]

@timomayer do you mean you don't have any (build) tasks running in those repos?
If not, I would still like to propose that we check those project by hand (fulltext search over the project) and copy those bower component files into the project, into the /bower_components folder and push this folder to Git
