tinymce: Do not include content.min.css as part of the bundle

[frapell]

This PR fixes gh-838

[petschki]

@frapell maybe this can be merged with the test-fixes from PR #853

[petschki]

@frapell travis is green. pull-request-5.2 breaks due to a plone.restapi issue which doesn't belongs to us plone/plone.restapi#552 ... can we merge?

[frapell]

I would say so... @jensens or @thet ?

[jensens]

Yeah, merge!

[petschki]

@frapell who recompiles the resources to the 5.x branches? regarding fixing plone/Products.CMFPlone#2430

[frapell]

@petschki I was going to do it sometime over the weekend... but if you have the time and want to do it, go ahead :)

[petschki]

@frapell uh ... if you give me some advice how to do this I'll do my best. I know how to build the bundles, but where to copy theese resources over? is there some developer documentation on this? thx.

[frapell]

@petschki Yeah, documentation for this is a bit hidden... You can find it here https://github.com/plone/Products.CMFPlone/blob/master/DEVELOPING_BUNDLES.rst

I was not able to do it myself over the weekend, however if you wait for me to wrap #850 (I hope to be able to put some time into it this week), I can include both changes... Or if you want to give it a try, go ahead :)

[petschki]

thanks for the docs ... for now I'm fine with waiting 😉
